Hi, Olin, I have some differences in my Pherigo data from what you wrote that I thought I would share.
I show that Mary "Polly" Pherigo is a daughter of John Pherigo, and a granddaughter of Robert Pherigo. Our family Bible shows that she was born Jan 18 1813.According to "Indiana Marriage Records" she was married to John Hall on Nov. 1, 1832, in Jefferson Co., IN.
Other researchers indicate that Robert Pherigo was married to Elsey unknown, but have no sources to back that up.
John Pherigo was married to Martha "Patsy" Adams and Mary "Polly" was 1 of 11 children.
