Joe,I have not found any connection to john R.B. Tisdale in my family however i do believe there must be.also i have not found anything on William A Jr. that married Mary B. Ford in 1822.My ggg grandfather Renison 1761-1811some of his children were married roughly between 1811 & 1825 which may put William A.Jr. in that same age bracket.Actually i have just been updating my direct line(genforum 357 is correct but there are some omissions).I hope to get more involved after xmas.We have a good Virginia Genealogy Library in Alexandria and Fairfax County and sometimes our local chapter carpool over to DAR library in D.C. and to State Library in Richmond. I am beginning to think my Renison is son of a William and brother to Henry,Thomas Nancy Ann and Polly. HENRY WAS GDN OF Renison's and Thomas's children, Nancy Ann Tisdale Wilks willed everything to Polly's and Thomas's orphaned children and brother Henry was Exoc. Renison was a Co Exoc of Minor Wilks will along with one of Minor's Sons. I'm getting more interested in others. If i find anything helpful, i will let you know.
