It says he “sold” the Club to his wife in 1944.Doesnt make sense that chips are ordered in 1938 with the “M” on them unless he was planning ahead?
Bernard was the father. Not sure if they called him “Ben”. Or if Ben was the guy listed just above Bernard in my first post? Not my area of expertise.....but Kentucky seems like a great place for research 😀

I don’t see any other significant “M” other than his wife.
