Thank you for replying. Yes, I found Wiliam G. Smock's memorial on FindaGrave with year of birth as 1795. At first I had 1802 which came from the census, it was good to find a correct date of birth.
William's first wife Mary Coff died on the way to Illinois. His son Fulcard C. Smock died in Carlinville, IL. A bio or obit said he had one daughter however I found two daughters and a son Fuller C. who died in Missouri. I found a daughter Elizabeth aka J. Libbie who died in 1920 at Edgar, NE. while checking my great grandfathers brother Barnet Smock who was born in Rostraver Twp. Westmoreland Co., Pa and died in Clay Co., NE in 1908.
