I just found the marriage record for Joseph and Pearl. Pearl's maiden name was Williams. They were married 7 Apr 1907 in Johnson County by J. S. Stout J.P.
They are also buried in the same cemetery as Jady Proffitt
Joseph L. Proffitt
Sept 9, 1889-Mar 16, 1962
Sept 29, 1892-July 17, 1953
Hope this helps.
