Hello John, I am a grandnephew of Elmer Blanchard Piatt and his wife Helen Piatt(Silfies). I am trying to figure out if Jane Cain is Elmers mother Jennie. Elmers fathers name is William Clint(on) Piatt. Elmer, who used the name Jeff in his adult life(?), had one son Jeffrey that passed away at age 17 in 1959. All members of the family are now deceased. I have some photos and death records, etc. Jeffrey was like an older brother to my father and I am just trying to trace this side of my distant relations. I can help if you would like any assistance in the Kankakee county area. By the way Helen was my grandfathers sister, that is how I relate to Elmer.
