Do you have females in your family tree who have few records and have left even fewer clues to their origins? You may have a maiden name and an estimated birth year, but there may not be any marriage record. Perhaps birthplaces conflict with one census naming one state and...
Today’s episode of Research Like a Pro is about the difference between endogamy, pedigree collapse, and multiple relationships. We discuss examples of each scenario and how it affects DNA matching and cluster analysis. Transcript Links Endogamy, Pedigree Collapse, and Multiple Relationships: What’s the Difference and Why Does it Matter?...
Would you like an efficient method to find clusters of DNA matches relevant to your research subject? In this series, I’m sharing the steps to create a network graph using the free, open source Gephi application, available for Windows or Mac. I use Gephi to create network graphs of my...
Today’s episode of Research Like a Pro is a case study of how increasing coverage of Barsheba Tharp and Joanna West, Nicole was able to confirm the hypothesis that Joanna was Barsheba’s mother. We talk about the challenges of working with DNA further back in time, but how adding...
I am sure I am not alone in finding that I constantly have more to learn when it comes to using DNA in my genealogy research. For example, I have defined many situations in my DNA research as pedigree collapse. However, after reading Diana’s post Endogamy, Pedigree Collapse, and Multiple...
Today’s episode of Research Like a Pro is about autosomal DNA coverage. We define the term, discuss why it’s important, and share examples and formulas. Learn how you can find more relevant DNA matches when you include additional test takers who descend through unique child lines. Transcript Links Find...
Do you have DNA matches that seem to belong in multiple genetic networks? Are you nervous that you’re seeing pedigree collapse or endogamy? Before you despair, realize that this phenomenon could be due to DNA matches sharing more than one common ancestral couple with each other, or what’s often called...
If calculating coverage of your research subject sounds challenging, try using this coverage calculator! In my two previous posts about coverage, we talked about the concept of achieving better coverage of your research subject through gaining access to additional test results of their descendants. I talked about Paul Woodbury’s coverage...
Today’s episode of Research Like a Pro is about the challenges of colonial research in the southern U.S. We discuss two things to help, and a case study. Join us as we talk about annotating historical maps and discovering legal context. Diana shares about our ancestor John Carey Royston,...
Do you have several research logs, reports, and other research tools for your ancestors that represent months or years of research? Do you ever forget that you’ve created a tool such as a timeline only to recreate it? I set up an Airtable base to track my research projects, and...
