I recently found my great grandfathers death record and his parents were John and Sarah Rist from Tyrone Mills in Fayette County in Pennsylvania.
My great grandfather was Joesph S. Riste and his wife was Sarah Garver from Dunbar area.They moved several times going west, started having their family in Toulon, Illinois where my grandfather, Allen Mathew Riste was born. (Joesph put an "e" on his name after an argument about religion by legend when he left Toulon and can be seen from the 1870 census to the 1880.
I have records and pictures for anyone that would be interested; (if related.)Thanks, Vikki
