This is a Message Board Post that is gatewayed to this mailing list. Surnames: Barr, Groff Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/rw/oVC.2ACIB/1154.1176 Message Board Post: Jane Evans Best has done the most extensive research on the Barrs including this line. I am also descended from this Martin. Can you get the Pennsylvania Mennonite Heritage quarterly from Lancaster County, PA.? Have you tried Ancestry.Com for the Barrs, Groffs, Bowman, etc.? Mrs. Best is co author of two Groff books, both of which she has updated with research in Switzerland and Germany. Hope this helps.
