Hi I am of a Hollis family from Sheffield. My dad was born in Attercliffe, Arthur born 1927 and had two brothers Henry (Harry) & Jack (I think his birth name was John). Their mother’s name was Emily (Millie). There are several other of us now. I wonder if there is any connection? co incidentally I’m looking for information on a great Uncle of mine? Arthur Hollis (brother of my Grandad). He use to ride his horse around Sheffield in the 1920s/30s in full uniform and welding a sword. I’d love to know if anyone had any pictures? Odd bits of info etc?
