Hi Janet. I was born in that community in Holmes County and yes, this is the same family. I have a good bit of info. I will share and would really like to see what you have.
William Riley Petty was father of my grandfather John Thomas, Sr. and his younger brother Jasper Newton "Babe." I used to play in the cemetery around Jasper Manning and Clifford Petty's graves:)
Please contact me when you return home and we can exchange notes by email.
Nice to hear from you and best regards,
