I just ran across your post while researching this family. William and Margaret are direct ancestors of mine, through Hannah C. I know that William and Margaret are buried in Little Salamonia Cemetery near Portland, Indiana. I've been there, seen the tombstones, have the pictures. I have Margaret's maiden name as Stohl, but do not know where I got that - no solid source. Please email me at email@example.com
if you would like to compare notes on this family.
