I found your article interesting in the fact that I don't believe I have heard from any Chew from the Brittish Isles. I have heard much that there were none there and may not have ever been. In any case it is nice to know there are indeed some Chew lineage still there,
Regarding the Chew in films, your indication of a Robert Chew may or may not be correct, I don't know. I do know there was a Richard Chew, a decendent of the Philladelphia Chew's, that I believe was a director and was listed as one of the first credits in one of Star War movies. I believe it was the first on. I just thought I would pass that along.
Personally, I am an Indiana (US) Chew. My line has been here now for 6 generations. As a matter of fact I live within 4 miles of where my ancesters have all lived, most of them farmers and I am a high school math teacher.
