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 Nicole (2s): This is Research Like a Pro episode 222 Endogamy, Pedigree collapse and multiple relationships. Welcome to Research Like a Pro a Genealogy Podcast about taking your research to the next level, hosted by Nicole Dyer and Diana Elder accredited...
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 additional test takers helps with that challenge. Transcript Nicole (1s): This is research Like a Pro episode 221 Autosomal DNA Coverage part two. Welcome to...
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 Nicole (1s): This is Research Like a Pro episode 220 Autosomal DNA coverage, part one. Welcome to Research Like a Pro a Genealogy Podcast about taking your research...
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 AncestryDNA matches, but you can use matches from other companies as well. Throughout this series, I will be using my own matches from AncestryDNA, but...
Today’s episode of Research Like a Pro is about Nicole’s research findings about Joanna West. This is a continuation of episode 216, where Nicole shared her preparatory steps for using DNA evidence to test the hypothesis that Barsheba Tharp was the daughter of Joanna West. She tells about the deeds and estate records she found for Humphrey Arnold linking him to his children and heirs. She also shares the DNA matches she found who...
You may have heard the terms endogamy, pedigree collapse, or multiple relationships as you’ve been learning how to use DNA with genealogy. What does your match list look like if you have any of these scenarios? What do your cluster results look like? How do you work with those DNA matches? What does this mean for your research and analysis? This article will help you understand each term and give you examples to digest. I’ll...
Today’s episode of Research Like a Pro is about Nicole’s research to test the hypothesis that Joanna West was Barsheba Tharp’s mother. She worked on this project for the 4th Research Like a Pro with DNA study group and shares her progress on each step. In this first part, Nicole shares her objective, clustering with Gephi, collaborating with a West researcher, the limitations of using DNA evidence for people who lived in the 1700s, making...
Today’s episode of Research Like a Pro is about Diana’s takeaways from the Advanced DNA Evidence course coordinated by Blaine Bettinger as part of the Genealogical Research Institute of Pittsburgh. We discuss Big Y-DNA testing, small segments, outliers in the Shared cM Project, confirmation bias, and endogamy. Transcript Nicole (0s): This is Research Like a Pro episode 213 Five Takeaways from an Advanced DNA Course. Welcome to Research Like a Pro a Genealogy Podcast about...
In my last post about autosomal DNA coverage, “Find More Ancestors with Autosomal DNA by Increasing Coverage,” I discussed how testing multiple descendants of your research subject can help you find more relevant matches. I shared some examples of applying Paul Woodbury’s coverage formula and the Daniel Arnold project I’ve been working on. Today I have an example of how expanding the coverage of Barsheba Tharp helped solve the identity of her mother. Barsheba Tharp...
What is the value of taking an immersive DNA course from an expert in the field? New perspectives, information, and practical applications to genetic genealogy. I completed the Advanced DNA Evidence course coordinated by Blaine Bettinger as part of the Genealogical Research Institute of Pittsburgh. The course exceeded my expectations, and I took copious notes on the latest and greatest advances in DNA as it relates to proving and confirming our ancestors. I highly recommend...
