looking for info on William Armstrong's wife, Elizabeth mcCutchin Adair. They were both born in Ireland and came over on the Louisa from Londonderry to Pennsylvania. They had 12 children, most born in Pennsylvania. The Armstrong family history goes back pretty far, but I have hit a brick wall with Elizabeth mcCutchin Adair. She was born in 1791 in Down, Down, Northern Ireland and died in Sept 8, 1848 in Miller's Run, Pa. William didn't die until 1867 and that was in Indiana.
