Thanks for the information. I knew Harvey's first wife, Llewellyn Barkley Gross, had a sister named Marcelle Barkley Herz (and they both died in 1964), but I didn't make the connection that Howard Herz was her son.

I'm starting to think that everyone who worked at Harvey's casino was in some way related to him. (Harvey Gross's cousin Chuck Lindekugel was his head of collections, his daughter and son-in-law, Beverlee Gross and Bill Ledbetter, were on the board of directors of Harvey's, Harvey's second wife's daughter and son-in-law, VeraLou and Richard Kudrna, both worked for Harvey's, Harvey Gross's grandchildren worked for the casino, etc.).
