Roxie, Sorry to hear about your troubles with Cystic Fibrosis.No, no one in our extended Abbott family has been afflicted.
The link to the DNA Abbott surname site is below. (Look at the "y-Results" tab.)I don't know if any descendents of Thomas Jefferson Abbott are participating. I don't believe they are. The number of participants are growing, and the more people who participate, the more connections can be made!
One other thing...the only thing passed down about the Abbotts my mom can remember is that the family was "originally from New England".
