Ansley's Father, Addison C. Fox and his family with his second Wife (he was 53 and she was 26 when they married in 1890) lived at 313 North Carey Street in Baltimore from 1899 until Addison died January 23, 1911.
Ansley's younger brother, Harry Hunter Fox, also lived there until his death in 1910.
The only picture I've found of Ansley from his Parker gun years is this one --
but, no gun.
