[using my mother's account to respond....]
This is a very old thread, but I'm still hoping to connect.
Jesse Senff was the youngest child of William S Senff and Anna Kazia Kitch of Marshall County, Indiana. The oldest child was Phillip Richard Senff, who married Martha Shaffer. Their oldest was Ben, his oldest was Ardella Jensen, her middle child was my father Bill Jensen.
I have a good deal of Senff family photos going to back to Phillip, Jesse, and William. You can contact me at my website TYSTO.COM.
