I am looking at a family tree done in 1995 by Chaping, Cook and Gray.This tree shows my ancestor James as married to Mary flack.All other records from descendants of this James show Ann Caldwell as his wife.
Is there another source from which you got the name Mary Flack?Can anyone verify for certain this was the wife of James Wherry b. abt 1715 in North Ireland to David and Mary(Leonard)Wherry?This family came to America ca 1718.
Also, it has been determined that James did not have a daughter named Sarah but did have a granddaughter by that name born to his son James b. abt1756.The senior James did have descendants living in Washington Co., PA and possibly Lancaster Co.His youngest son, David b. 1757 lived for a short time in Straban Twp, Washington co., PA.
Hope this gives you more to work with.If we are on the same branch, let me know.
