Based on my experience with DNA testing I'm impressed. Not everyone is, including long time genealogy newsletter writer Dick Eastman, as I found out during a brief conversation on Saturday. Dick sees a role, but isn't an enthusiast.
There are just too many good stories about people who have made breakthroughs on intractable genealogical problems to dismiss genetic genealogy. A new one was briefly related to me by a member of the British Isles Family History Society of Greater Ottawa on Saturday, and a goodly number of them are found at the web site for the International Society of Genetic Genealogy. Take a look.
Will genetic genealogy turn out to do for genealogy in the next decade what the internet has done in the last? There's a chance.
