Welcome to Jamie Dinsmore who I invited to the project since he has a lot of profiles among the Scotch-Irish in Virginia.
I thought it would be interesting to state our individual interest. I am the descendant of the Petticrew family who came to Dauphin Co, Pennsylvania and followed the road down to Rockbridge Co., Virginia where James Petticrew met and married Sarah Kenney. They then headed up to Montgomery Co., Ohio. I have a project on the Pettigrews (with a "G") of South Carolina and Ireland who recent Y-DNA studies have shown are related to my Petticrews (with a "C"), just as my great-grandmother claimed.
I don't know the background of the Kenney family, but they may or may not be related to a well-known Kenney family from Rockbridge Co. that project collaborator Justin Swanstrom is an expert on. That Kenney family moved on to KY.
One of my questions is why I have so many Southern (TN, KY, GA) DNA matches. I assume that they are due to Petticrew / Kenney and other Scotch-Irish ancestors whose descendants moved from westward from Virginia. I hope to learn more ancestor surnames eventually.
