Thank you for spelling his name correctly, at least, edgar.
Roy Rogers was born Leonard Slye somewhere in Iowa (this is all off the top of my head; you can look up exact dates and locations in Wikipedia, of course, if you wish.) For most of his adult life he was married to Dale Evans (probably also not her real name), his co-star in most of the Western movies he made. They had a child together who had Downes Syndrome (at the time a child so afflicated was called 'Mongoloid', an ethnically un-PC diagnosis, now totally out of use).
I didn't want to call Finn out on this but I snickered when he listed Roy as a fictional person.
If memory serves, Rogers started out as a country and western musician, a founder of the Sons of the Pioneers, but he had what Hollywood thought was a good on-screen presence and made him a Western star . He was popularly known as 'The King of the Cowboys.' I don't think anybody over the age of, say, six or seven ever thought of him as anything but an actor. (He had a reputation, though, for being a fine horseman and a very good shot with a pistol. But that could have been just press agentry.)
