This is a long shot but here goes...
my dad died a few years ago and i've just started looking at creating the family tree. When he was young he remembered on at least a couple of occasions playing with a "quiet" lad called paul mccartney when he was brought to a pub where my dad lived, in the company of someone called "aunty dill". my dad also believed that aunty dill was related to or at least known to his/our family, and indeed he also referred to her as aunty dill. He later remembers her saying that paul would often "send a car around" when the Beatles were playing nearby!!.
My dad wasnt one to exaggerate or make up stories. I've done some digging and worked out that Dill was actually Hannah Dilys Jones and she married paul's uncle bill mohin (actually named owen michael mohin, bill was a nickname) but i cant find out anything about Dill's family. She has now passed away.
i'm intrigued to find out if dad/dill were related, but noone left on dad's side to ask. Short of asking paul himself - and even if i could i'm sure he's got more important things to worry about- i've come to a grinding halt. Hence this post. If anybody does have any useful info it would be appreciated (and held in confidence, obviously.)
