As you may or may not know, like a family dynasty, many in "The Industry" have direct and in-direct family connections. Many known in "The Biz" by their stage names, but there are quite a number of them that have ordinary and/or names that are too close to one another?
As an SAG Acttor-Performer myself, (under the name "Ed Moch"), I have come across this many times with my own association.
From time to time, I was aquainted with Hollywood Chamber of Commerce, "Johnny Grant", who before his passing some years ago, knew them all.
In a sign of respect, I continue to keep the tradition down and around The Hollywood Walk of Fame, when visitors (tourists) walk around the area.
My cousin Jenny Kane@geni.com has worked with Steven Speilberg for over 20 yrs. Another cousin Anne Kane@geni.com whose son is Charles Collier started the Simpsons with his cousin Joey who is Jenny's brother.
We also had a female comedian in the family that used to be on Sat. Night live Judy Tenuchi. People do not believe me when I tell them this but it is all true. Jenny does all the lighting for every single movie that Steven Speilburg has done. After developing the Simpsons my cousins' children started "King of the Hill" which I'm not sure is still on. Of course we all know what happened with the Simpson's as there is now a PO Stamp reflecting Homer!!
