You can see by this link there was one George Van Hoven, at least. He was born around the right time. I have found this George Van Hoven was born in Brooklyn in 1915 in Brooklyn and died in 1994 in Las Vegas. May be a gambling connection.

Can't find anything online (ok, on google) about Vaughn. I hope this is a start.
