Carla,
This is SO belated (sorry, life has intervened) that I hope you get it & can reply. My new email =

You're right, it was JOSEPH, not THOMAS, Bashur Clapper to whom Hattie Pfahl was married. Their son Harold (Hal) was my stepfather.
Do you have any more information on Richard Maxwell Clapper? I remember being told that he was a talented musician who traveled in vaudeville, but that's all I know.
Best, Barbara
