Book Review: “DNA for Native American Genealogy”

DNA for Native American Genealogy - Genealogical.com

When the esteemed Roberta Estes of the DNAeXplained Blog writes a book about DNA, there is a justifiable expectation that the work will be accurate, informative and definitive. Among Ms. Estes many accomplishments are launching the Million Mito Project and being a National Geographic Society Genographic Project affiliate scientific researcher. This is a very thoughtful book, intended to put actionable information in the hands of readers that will guide them through the process of learning about Native American genealogical research.

Determining Native American ancestry from DNA testing is not necessarily the easiest task. Ms. Estes takes the reader through comprehensive steps to examine how to work with ethnicity estimates, autosomal (atDNA) matching, mitochondrial (mtDNA) and Y DNA in identifying Native American DNA.

Part 1 is informative, containing an overview of the concept of tribal membership and asks readers to consider their goals for determining membership. Ms. Estes’ thoughts about cultural appropriation are well advised, and challenge each reader pursuing this research to think about the topic.

In Part 2 readers experience topics in ethnicity and population genetics. As both a professional scientist and genealogist the author is able to take readers as deep into genetic topics as they want to go. Her goal is for readers to understand the topics at a comfortable level, and she provides examples with clear illustrations.

Part 3 gives specifics about how to use the autosomal tools at major vendors in the search. The mitochondrial DNA portion of the book (Part 4) and the Y DNA portion of the book (Part 5) discuss the relevant ancient and modern haplogroups, sharing in detail which occur in Native American populations, and their tribal affiliations. These parts include maps of where the haplogroups are found. Part 6 is a roadmap and checklist which guides readers through the journey of investigating Native American ancestors through the use of DNA.

As with every book I review, I read this book from cover to cover. Given that my ancestors’ paper trails and our family’s genetic results show no indication of a Native American ancestor, a friend stepped in to help. His family history contains a story about an ancestor who was a member of a specific tribe, without any evidence. The story of this ancestor is currently unknown prior to a marriage that took place in Colonial America. He was willing to let me use his test results to see if any information could be found in his DNA that might potentially shed light on this family story, with his goal being genealogical information. The ancestor was not in his direct matrilineal or patrilineal line, so I turned to Part 3 of the book. Given how many generations back this ancestor had lived, the existence of identifiable regions of Native American DNA was doubtful. The history of the area suggests that the ancestor may have been a descendant of a tribal member rather than a tribal member, which lessened the chances of uncovering a segment.

My friend had tested on Ancestry, and then transferred his test results to FamilyTreeDNA, then had unlocked his autosomal transfer in order to use the ethnicity tools. First, I used the FamilyTree DNA myOrigins® (version 3) as shown in the book. As we had anticipated, his results showed 0% origin in the Americas. (His results also showed 0% Asian origins.) Opting in to Compare myOrigins® showed some interesting information for him to consider with his other matches. Part 3 also clearly walked me through the options within the Chromosome Painter to see a visual representation as well as how to view the locations of the chromosome segments. Next, the book took me through the features of using ethnicity information on Ancestry, with explanations about the Genetic Communities. Ancestry provided European matches, but no other traces of matching other parts of the world. Had Native American DNA segments been identified in my friend’s DNA, I would have known what to do next and how to do it. Although DNA may end up a part of the solution to my friend’s question about his ancestor, this family story will take more time and effort to prove or disprove.

Even though this particular case was not successful, there is clear value of this book to educate readers and  guide them through identifying the appropriate steps they need to take to research known and potential Native American ancestors through the use of DNA.

This book picks up where the theories end and your work begins. The book contains references to source material, including Ms. Estes’ DNAeXplained blog, for those who want to go deeper into learning about the topics that are presented. For those who want to incorporate genetic genealogy into their Native American genealogical research, this book will be a complete introduction and will also serve as a reference during the research process. Readers will find the haplogroup references to be very useful in their research. The completeness of this book truly is, as Ms. Estes describes it, a labor of love.

The book is available at Genealogical.com and other booksellers.

You can search the 1950 US Census!

Blog Banner - You Can Search the 1950 US Census

Searching the 1950 US Census will be an awkward and cumbersome search until every field is indexed. But you can give it a try.

Be sure you to navigate to the search page:  https://1950census.archives.gov/search

The 1950 US Census NARA Search Page



The search has limited features that include: name, state, county and enumeration district. You do not have to enter search terms any field. For example, you can leave the county or the enumeration district blank.

1950 US Census Search Inputs


If you cannot see the population schedule sheet for the search result on the right, click on “Population Schedule” to see the actual census sheet.

Of course I had better luck in small towns with families having unique names. Just as in any census, try to search for unusual family names. I have even had some success searching boroughs of New York City.

How about a quick hands-on exercise to find a name on the census? I have a simple example using my favorite poet, Ogden Nash.


Name: Frederick Ogden Nash
State: Maryland

1950 US Census Search fields for Ogn Nash


The first result on the right-hand side, listed Odgen Nash (rather than Frederick Ogden Nash) and showed him with his wife Frances, and his children Linell and Isabel. Note: this result came up without entering a county or enumeration district.

On the bottom of each search result is the “Machine Learning (AI) Extracted Names” section that can help by showing you the names that appear on the same census sheet. The AI-generated indexing was surprising to me because it does try to offer alternate spellings of names.

To download the sheet, click on the three dots that appear under “Help Us To Transcribe Names” to see the option to download the sheet.

Option to download

Only the first entry is expanded. If your family member is in one of the other entries, click on “Population Schedule” to see the actual page of the census.

Multiple results (unexpanded)

And the population schedule for that result will expand. (Only one population schedule sheet will appear in the results on the right at one time.)

Expanded Population Schedule

I have posted a short video on our YouTube channel with the example search in action at: https://youtu.be/rLgq2nqNmbA

Let me know how you do.

It’s Been Confidential for 72 Years: The 1950 Census

It's been confidential for 72 years: the 1950 Census

There’s been great information published about the upcoming release of the 1950 US Census. I have been collecting it and want to share with you a reference of helpful resources, along with activities that you can do to prepare for the release!

Important date: 1 April 2022

What is going to happen

The 1950 US Census will be released, 72 years after it was taken.

The National Archives and Records Administration (NARA), Amazon Web Services (AWS) and Artificial Intelligence will give us an initial index including name and locations on the day of its release. The AWS artificial intelligence/optical character recognition (AI/OCR) Textract tool is being used to create that initial index. The index will be available for the P1 Population Schedule and the P8 Indian Reservation Schedule. Since the index will probably not be perfect at first, the National Archives asks us to submit name updates to the index using a transcription tool that will be available on the 1950 Census website.

Interesting facts about the 1950 Census

5% of those responding were asked additional questions, including those about where the person lived a year ago, education, employment, marital status, military service (for males) and the country of their parents’ births.

An exciting fact about this census was that it was the first time Americans abroad were enumerated. In practice the enumeration of Americans in the armed forces, US government employees and vessel crews were counted more reliably than others living aboard. Family and neighbors might report others living abroad.

It would also be the last time that enumerators went around to large multifamily dwellings. In future, the blank forms would be mailed.

What’s different from past census releases

Last release: 2 April 2012. We had to wait an extra day because 1 April fell on a Sunday!

The 1940 US Census was made available to us unindexed. Digital images are great, but without an index you had to identify a set of images to look at, then look at each image to see if your family member was on it. The process involved people figuring out the census enumeration district in which their ancestor lived, then going through the pages for that district page-by-page and line-by-line. Simultaneous with the release, volunteers and genealogical record companies began creating indexes, transcribing the census line-by-line and page-by-page. More than 163,000 volunteers were organized by FamilySearch and managed to create an index for the more than 3.8 million images in a lightning four months. (If you have not been part of a FamilySearch indexing project, please consider it. It is an amazing thing to do. Two indexers transcribe data, and a third arbitrates any differences between the two transcriptions.) This time, on the day of release we have an initial index of names and locations, which will be a good starting place.

This year, for the first time, those who have over 165 terabytes of available computer memory and download the whole census dataset in bulk.

What you can do now

1. Bookmark NARA’s 1950 Census Records webpage. That is where the link to the dedicated website will be posted.

2. View the Questions Asked on the 1950 Census and also view samples of all the Census Forms in the 1950 Census Dataset.

Census Forms in the 1950 Census Dataset

You will probably want to start with: Form P1 – Census of Population and Housing (front). The back of the page with housing information was not microfilmed, and only aggregate data exists.

3. Watch the videos at the National Archives Genealogy Series: 1950 Census and download the handouts. Previous presentations have been recorded for later viewing.

4. Gather blank questionnaires and fill in the censuses during your lifetime. Imagine how glad you would have been if your ancestors had done this for you! Head over to the US Census Bureau to learn more about the Censuses and Download census forms at the Decennial Census of Population and Housing by Decades.

Decennial Census of Population and Housing by Decades

On each page for the decennial census, there will be a link to download that Decennial Census Questionnaire & Instructions. From that page you can download a sample questionnaire. Or you can go directly to the 1950 Census page where you can download blank forms and view the index of questions.

Census Bureau 1950 Census Page

On the Through the Decades webpage you can find a link to download “Measuring America: The Decennial Censuses From 1790 to 2000” in that includes information and questionnaires from the 1790 up to the 2000 US Census in pdf format.

Through the Decades download page

On 1 April 2022

Travel to the NARA’s 1950 Census Records web page, where there will be a link the dedicated website.

Many thanks to all those at NARA who worked tirelessly throughout the pandemic to bring this data to us on time.

RootsTech 2022 lives on

Another RootsTech has come and gone, but RootsTech 2022 is really is not over! The classes that were recorded for RootsTech 2022 are still available. In fact, RootsTech made a decision to keep classes online for 3 years (unless the content creator asks for them to be removed). That means you have access to content from 2021 and 2022. Be sure to have a free FamilySearch account so that you can create a playlist as you search for classes.

The web address is https://rootstech.org. Use the menu on the upper right corner and select the option “Sessions” to search for sessions, or “Speakers” to search for a particular speaker.

RootsTech Home Page

When you search for Sessions, there will be a search box on the top and a list of filters on the left side of the Session page. I find using the filters more cumbersome than searching, but viewing the topics available can be helpful. To use the filters, click on the down arrow next to a filter to see the options available. After selecting an option, the available classes will show up on the right side of the screen.

Search for Sessions page

An example search for the term: military will have our military classes.

Search results for: military

Most of the classes have a downloadable syllabus or handout, and you should be able to find contact information for the instructors if you have questions.

RootsTech Connect was an overwhelming success, with 700,000 people officially registered. More viewed sessions without registering. Expect that there might be a virtual component in any upcoming RootsTech, which is great news for anyone who cannot travel.

Thanks to those who stopped by virtually to visit my classes at RootsTech, and left a greeting or a question.

Archaeology and Genealogy

Archaeology and Genealogy

This past semester I took an introductory class in archaeology. Archaeology is part of anthropology, so the class involved more than digging. I learned that archaeology was one of the four branches of anthropology, with the other three being: Physical (Biological) Anthropology, Cultural Anthropology and Linguistic Anthropology.

Archaeology and genealogy share some similarities. Like genealogy, archaeology looks at peoples and their cultures through the physical things that they leave behind. Historical archaeology is most like genealogy because it covers the time of recorded history.

Archaeology borrows three principles from geology: the Archaeologists use principles from geology to determine time frames of artifacts: the Principle of Superposition, the Principle of Association, and the Principle of Strata Identified by Fossils/Artifacts.

The Principal of Superposition is where the oldest artifacts are at the bottom. Just as genealogists begin with themselves and work backwards to older ancestors, an archaeologist digs through layers, from newest to oldest and the story is the sum of those layers

The Principle of Association means the materials that are close together are of similar age. This reminds me of the collateral relatives that genealogists research to find answers, and cluster research.

Principle of Stratification lets archaeologists estimate the age of artifacts by the layers in which they are found. Genealogists dig through the layers of each generation to find their ancestors and families.

Digging a site is a destructive process, where genealogy is constructive. Genealogical work is similar to archaeology in the way that it uncovers the artifacts that are combined with their context to build the story of how people lived and moved through their space. Unlike genealogy, digging a site is destructive. Once a site has been excavated, it is destroyed. (It may be possible to virtually reconstruct a site through the use of technology.) Similar to genealogy, when little is known about an ancient culture, archaeologists begin with what is known about the present and work backwards.

Context is incredibly important in archaeology. Having an artifact without understanding where it was found and what was around it robs it of most of its value. The context of our ancestors’ lives is what gives our work its value. Understanding their lives and times, the challenges they faces is the richness on genealogy.

Next semester on to Physical Anthropology which promises to discuss inheritance and DNA testing.

Be a family history archaeologist and uncover the stories of your ancestors!
