I have seen the surname Casto on list several times. I have not researched this family yet but know they are married with Slaughters. Anyway, I found this in EARLY ART AND ARTISTS IN WEST VIRGINIA by John A. Cuthbert and thought it might help someone. CASTO, SALLIE Active 1889-1913. Casto was a landscape painter active in the decades surrounding the turn of the twentieth century. The West Virginia State Museum possesses several of her works. WVSM. CASTO, HOLLEY O. Active 1900 "Artist and watch repairer," aged 28, residing in Jackson County. Census. Bridgett
