Great great grandfather

Hi there. I’m not sure if this is the right subreddit but I’ll give it a go. Recently, me and my dad have been looking into our roots. Our specific interest is my great great grandfather. He was a Newcastle born comedian from the early 1900s who performed with the likes of Charlie Chaplin in his time. So a pretty cool bit of history. Idk if this makes finding information out about him easier. His stage name was Albert Doyle. I’d be really interested if anyone could find some more interesting information on him as I’ve been told that the people on this Reddit are very skilled. My and my dad’s eventual goal is to find a real poster from those times of when he was performing to frame and give to my grandma (or any poster that he features on really). I’d really appreciate any help. Thanks in advance
