Hello Sandra, Only two of the persons you mention are buried in the Wiseman Cemetery (AKA McKendree Cemetery) in Perry Twp. Gallia County, Ohio and they are Isaac Wiseman II and his wife Mary Magdaline (Armentrout) Wiseman. I have submitted pictures of this cemetery and all the tombstones to the "Find-A-Grave" site and you can see them there.This cemetery is off the road in the woods and is hard to see especially when the leaves are on the trees.
Samuel Handley and his wife Elizabeth (Barger) Handley are buried in another Wiseman Cemetery up John's Creek Road off State Route 141 near Sheritts in Symmes Twp., Lawrence County, Ohio.Isaac Wiseman III(my great great grandfather), son of Isaac II & Mary Magdaline (Armentrout) Wiseman is buried in this cemetery also. I think Jane (Slagle) Handley is also buried in this cemetery but there may not be a marker for her.
I may have confused you on the numbering of the Isaacs as the Wiseman Family Association has dubbed the first Isaac as Isaac Sr. as he was not proven until after B.W.S. Wiseman's Genealogy was already in print.So the line as we have it goes: Thomas, Isaac Sr. (your Isaac I), Isaac I (your Isaac II) and it is my Isaac II who married Mary Magdaline Armentrout.I am the senior historian of the Wiseman Family Association and I have 3 notebooks full of descendents of John & Elizabeth (Wiseman) Slagle.
If I can be of further help to you let me know and I'll see what I can do.
Your kinsman, Robert Newton Wiseman Senior Historian
