The Barry G. Wallaces of Richmond, Tx

I am looking for any information on the ancestors of John H. Wallace (Born:12/15/1836 -- Philadelphia, Pa.; Died 12/22/1915 -- Philadelphia, Pa.) and his sister Anna M. Wallace Simpson (Born: 1840). John was married to Catherine Rose Murphy (4/19/1842 -- Philadelphia, Pa.; Died: 9/17/1921 -- Philadelphia, Pa.).

In addition, I am looking for any information on the ancestors of John P. Oliver (Born: 10/12/1844 -- Georgia; Died:8/30/1919 --Wrightsville, Georgia) and his spouse Melica J. Mayo (Born approx. 1830; Died ??).
