There is an ongoing debate about the mother of Ann Humphrey (1625-1695). John Humphrey, Ann's father was married to two women - Elizabeth Pelham and Susan Fiennes Clinton. I have seen websites claiming both as Ann's mother. What is the most efficient way/place to find known relatives of Elizabeth Pelham to confirm or deny her parentage? I have done DNA testing but not sure how accurate it is to relatives born in 1625.
