Among Gertrude's friends, and a performer in Tim Frawly's Stock company run by Busby Berkeley's father Francis Enos (who died when Busby was eight), were actress Amy Busby from which Berkeley gained the appellation "Buzz" or "Busby" and actor William Gillette, then only four years away from playing Sherlock Holmes .
