I don't know where it is. I know of a farmer who told me that ARTMANs are buried on his property in
Allegheny Township, but it isn't very close to
Markle. I have been a faithful customer in his store for many years. I asked if I could photograph the gravestones, but he just turned and walked away from me. All these "locals" tend to be very unccooperative. He told me the "
Allegheny Township Historical Society" went around and recoreded all the information from isolated burials on farms, and then made a report. I told him that those "old reports" get lost all the time." That's when he turned and walked away from me. None of these people care, really. By the way, I never even heard of that historical society.
As an alternative, you might want to contact
Victorian Vandergrift (loctaed in
Vandergrift). I would write them a letter and ask them to circulate it among their volunteers. One of them might know.
Another possibility is to see whether
Victorian Vandergrift or Apollo Librray have a "family history" for the
ARTMAN surname. Both of these places have family histories of surnames in the local area. These were donated by people who researched the surname. ARTMAN is a very significant surname in this area. If you try this you can just call those two places because all they have to do is walk over to the shelf and look for the
ARTMAN name on the shelf.
