I have Clarence's name spelled Keefer, and his wife's as Lula Jane Williams. Clarence was born 27 Oct 1899 in Milton, Cabell, WV, to Matthew W. Keefer and Minnie Jane Sergeant. Matthew was a son of Benajmin Franklin Keefer and Christina Alberta Williams, and was born 10 Jan 1873 in Putnam Co, WV. Benjamin was a son of Daniel & Elizabeth Keefer, and was born 2 May 1841 in [probably Wetzel Co] [W]Virginia. Daniel was from Pennsylvania.His family is found in Wetzel County in the 1850 census and thereafter in Mason County, WV.
I have lots on his descendancy, but his parentage is not proven.
