Thanks for the info. We recently had a descendant of Oney Stanley/Standley and Dorothea Sinnickson do a YDNA test. He matched our line, off one marker out of 37, but on a marker that is known to mutate often. Until we tested there was only one NC line that didn't descend out of the Beverly Ma Stanley line, so they were quite surprised when we didn't.
Several of us are also doing Family Finder testing, especially those that don't carry the Stanley/Standley/Standlee surname, and we've had some interesting Bilderback possible matches. We just got the Ydna test results back a couple of days ago. We were beginning to believe we were going to have to give up pursing this line, but our new test results have changed that.
