My mother's father (d. 1983) was Paul Minteer of Ellwood City, PA.His father's name was Andrew, who unfortunately cannot be the same as the Andrew referred to in your post (different first names of spouses).However, I am becoming fascinated with genealogy and am surprised to find such a coincidence regarding an Andrew Minteer from the same area as my own great-grandfather.
May I quote from the obituary section of The Ellwood Citizen, Thursday, April 2, 1908 (errors intact):
"Mrs. Margaret J. Minteer, aged 35, wife of Andrew Mynteer, died at the old Fisher Hotel last Sunday from callapse caused by a severe hemorrhage.Mrs. Mynteer is survived by her husband, and six children, the youngest, born a few hours before the mother's death.The remains of Mrs. Mynteer were taken to Torontoo Tuesday for buriel."
That child was my grandfather Paul.
I hear from family members that there are a number of Minteers buried at Gettysburg.If anybody back East has any information on this, or on anything I've posted here, please let us know!
