Leased his land for oil production as early as 1895. The May 31, 1895 edition of the Butler Citizen contains the following in the "Oil Notes" section:
"M. Fadden's well on the Whitmire was shot, and started off big, it will make from 25 to 50 bbls; rigs are up on the Thompson 10 acres. A Martain, Samuel & Dan'l Whitmire, and McFadden is building No. 2 on the Robert Whitmire."
It is unclear which Whitmire farm M Fadden's well was on. However, No. 2 is clearly being built on Robert's land.

Death Cert (#107613) has cause of death "Struck by R.R. Train. Accidental"
He was killed in train/horse&buggy accident. He was taking his daughter's family - the Shoup's - home to Butler following a visit celebrating his 32 anniversary. His daughter, Isabelle Shoup, was nearly killed, but recovered.
He was struck at 5:55pm by the Bessemer and Lake Erie Railroad (B & LE) #11 going southbound near the Oneida Station on a sharp curve. According to Bessemer records, the #11 was a 4-4-0 style engine.
