Claude and Nanny Markum lived in Houston, Texas. They owned a boarding house in Port Houston. Claude was an Irishman. Nanny was of Sweedish descent. They had two daughters Rosetta and Altie. Rosetta married James Abner Biggs. Any Info would be appreciated. I have been told by my father Jearold Allen Biggs that the Markums were once owners of "BUDDIES" or "BUDDY'S" food markets in the Dallas, Texas area.
