OK, thanks for looking.
I searched for and found Francis and Frances (his wife) Clyma's gravesite. I found their gravestones and I took pictures of the them. The gravestones are not in very good shape. The letters are wearing away. I took the pictures in late fall of 2006. Their gravestones are right across the street from the land they once owned in a small graveyard with a one building white church. It is located Southeast of Shullsburg, WI and Northwest of Apple River, IL. on County Rd W (on the Wisconsin side).
If you want I can send you the pictures of their gravestones.
