Genetic genealogy, like documentary genealogy, can result in negative findings and negative evidence. What’s the difference? (It wasn’t that long ago that I was confused about that too!)
You start with a research question and a source. ‘Negative’ means the information you’re looking for in the source isn’t found. A negative finding doesn’t help you answer your research question. Negative evidence does. You may have to understand the context to know which one you have. Some examples, with document-source genealogy and DNA-source genealogy, may help.
AncestryDNA Genetic Communities went live this week! What does that mean for my genealogy? (And scroll to the end for something free that expires April 6 2017!)
The previous post in this short series talked about the genealogy basics one should have covered before dabbling in DNA. Now we’re ready to explore how to use some of the DNA information in conjunction with that genealogy.
Last month I suggested that soon I’d be sharing some results of a citizen science DNA project I’m working on. However, I realize now that the proposed blog draft is too long, with too many diversions to explain some basics that might help newer readers.
So I’m taking a step back and planning several short posts first. The theme is ‘Using shared cM counts to help find the common ancestor.’
