Half-Day Hybrid Seminar
with speaker Dorothy Coltrin
Saturday, February 8, 2025
10:00 am - 12:30 pm PDT
The sessions will be recorded and available to view for two weeks.
Someone Stole My Family
If, in genealogy, you follow a common name, such as Graham, you might stumble across other people by that name. It might seem that they are part of the same family, but you need to be careful with your research. In Dorothy’s case with her Grahams, she found two incidents where this happened. In the first case, a historian for a town in New Hampshire decided to marry her ancestor to another woman and a set of children who are part of her family but not his. In the second case, a person applying for a Revolutionary War lineage thought his family was the one in the Battle of Bunker Hill, even if the patriot didn’t live in Peterborough, New Hampshire.
Use of DNA to Verify a Family Tree
Using the various tools of genealogy as well as biological evidence, Dorothy will show you how she established both historical proof and autosomal and Y-chromosome DNA evidence to connect her John Graham (before 1730-before l1787) of Hancock, NH to her Coltrin-Graham family.
