Have you wondered how you can use mitochondrial DNA in your family history research? In my last post, “Mitochondrial DNA – a Blast From the Past,” I wrote about mitochondrial DNA inheritance. This post will build on that foundation and explain how you can use mtDNA haplogroup information to discern between two possible women ancestors. You’ll remember that both men and women inherit Mitochondrial DNA (mtDNA) from their matrilineal ancestors. In other words, mtDNA passes...
This week, I learned about genealogical and historical records created before England created the civil registration system in 1837.[1] I’ve learned a wealth of knowledge that I look forward to using to confirm known ancestors and discover new ones through documentary research. The lessons made me think about confirming and discovering ancestors who lived before 1837 using DNA. Autosomal DNA can be used to research ancestors about 6-8 generations back in time. For me, ancestors...
Today’s episode of Research Like a Pro is about the DNA Standards in the Board for Certification of Genealogist’s Genealogy Standards manual. These DNA standards were added in 2019 as part of the second edition of Genealogy Standards. We discuss some applications of the DNA standards to our own work and ideas for how to meet them.

Today’s episode of Research Like a Pro is about writing a DNA proof argument. First we discuss three types of proofs: proof statements, proof summaries, and proof arguments. Then we talk about how to organize a proof argument that includes DNA evidence. We discuss figures and tables and how to include numerical data. Join us as we discuss how to write DNA proof arguments! Links How to Write and Publish a Proof Argument with DNA...
Today’s episode of Research Like a Pro is about asking permission from living individuals in your DNA reports and proof arguments to include them in your paper. We also discuss different types of sharing – private sharing and publication – and what permissions you may need to request. We talk about privatizing living individuals by removing personally identifying details, in case your message to request permission goes unanswered. Links How to Prepare DNA Research Reports...
Are you wondering how to tell if an AncestryDNA Thrulines estimate is reliable, or even possible? The Thrulines algorithm works by comparing your DNA matches, their trees, and all the searchable trees in the Ancestry public member tree database. If the algorithm can make your tree and your DNA match’s tree connect somewhere, the hypothesis shows up in Thrulines. One problem with this is the many errors in the public member trees database. Also, Thrulines...
It’s exciting to have new DNA analysis tools continually developed by amazingly smart and creative people! Hybrid AutoSegment is a brand-new 3rd-party DNA tool from Genetic Affairs. This tool gathers DNA segment data from 23andMe, Family Tree DNA, My Heritage, and GEDmatch together in one report. Having the segment information all in one place streamlines the process of examining, analyzing, and figuring out which of our DNA segments we inherited from specific ancestors. Now, we...
Are you up for an adventurous foray into DNA segment data and ready to use some programs to understand it, analyze it, and use it in your Family History research? Let’s go! You may have already read some Family Locket blog posts about using DNA segment data. The Chromosome Browser: A Tool for Visualizing Segment Data by Nicole, explains how to use chromosome browsers to visualize the DNA that you share with your DNA matches...
Have you thought about the steps to take to work through a DNA research project? Have you ever been stuck or lost during a project and wondered what you should do next? What do you do? I’ve thought about it a lot, and it motivated me to create DNA Process Trees that have a stepwise model/instructions/flowchart of the main steps to take when working through a DNA research objective. The steps help me maximize the...
