Maybe so but Admiral John Paul Jones was related to General Lew Wallace who wrote the book Ben Hur.You must read the book The Life of General Lew Wallace by General Lew Wallace.Then review the making of the movie Ben Hur in 1925.
Lew Wallace's family started out in Pittsburgh which was the home town of the very first movie theaters run by The Warner Brothers (Duquesne Amusement Company) on Churchill Road in Pittsburgh. The Warner Brothers moved to Burbank California with the Goldwin Mayer Myers and Selznick family in 1923.
I know for sure there is a connection to a Rambo family in the movie business so that is why I cast my fishing line in your coincidence pond.
I guess the first thing you must come to grips with is the Selznick family were a well known Jewish family from Pittsburgh and the Churchill, Clark, and O'Hara families were well know Catholic family from Pittsburgh connected to William Clark and his son Meriwether Lewis Clark.
