For those of you looking for the parents of the subject Margaret, wife of 1st Peter KIEFFER/COOPER and 2nd Andrew FEASTER, I found the following will: Lancaster County Mary 23, 1764 February 12, 1770 FRY, John Wife: Dorothea Children: John, Jacob, and Margaret wife of Peter KEEFER. Ex: George ARNOLD and Frederick SHAND Lancaster Borough I haven't seen this information elsewhere, so I can only trust that it's some good news!!! I believe the will was written in 1764 and proved in 1770.
