Devlin Family Genealogy Forum
I may have your Sarah.
My 5-great uncle John Devlin (1812-1881) had a daughter Sarah Jane Devlin who outlived both him and his wife Sarah Jerden. They lived near Brantford Ontario. I was under the definite impression that Sarah was unmarried at the time of John's will, and she is also the beneficiary of her mother's will (mother died in 1887). That not withstanding, I have a note from a descendant of John's that Sarah married someone with the last name of Clark; but I had thought they were childless. Since I don't have a lot of other information the family may have just lost track of her. Geographically, Brantford is not that far from southeastern Michigan.
I have recently gained a good deal on Sarah's family, so if you want some cousins let me know.
