She is my direct ancestor, daughter of Abraham and Hannah JOHNSTON/JOHNSTON. On her death certificate and her son's death certificate her maiden name is spelled "Johnson" but I can only find Abraham and Hannah's surname spelled "Johnston". Ann was later married in Wayne Co. to John KELSO in Nov./Dec. of 1831. Could you lookup that marriage, also?
If you can find out which township she was married, maybe I can find some siblings to trace.
