William Adam Vale - Photographer

William A. Vale was born July 1847 in Indiana. The 1870 census from San Bernadino County, Calif. shows William was a "photographer" at age 22. The 1850 & 1860 census show William was the son of Milton & Mercy Vale. The 1860 census shows Milton was an "artist."

I'm looking for Milton's parent's and ultimitely a connection to the Pennsylvania Quaker Vale's from the York Co. area.

Thanks in advance.
