WOW.
Thanks for all these replies! I really didn't expect to hear any this soon. I'm going to have a nosey through them all and read them properly in the morning. Just wanted to take a look and say Thankyou.
There is some more info I have, My Grandma (Barker) had a brother and a sister, her brother was D Barker and moved to New Zealand where he was a pilot I believe. She also had a sister R Barker who moved to London. Or at least somewhere local to London, not sure if it was in the centre or not.
Also from looking on Ancestry a little if the documents I've seen are for the correct Barkers who are related, then they a name of Hughes maybe her mothers Maiden name, and if that is true then she was also married to Robert Barker. Whos Dad was also called Robert Barker (apparently).
These names cannot be confirmed by any of my family, so I don't know if it's the right ones or not.
As for Grandad (Ambrose), he also had a few brothers, unsure of the names, but one of my cousins seem to think he one was called Jerry or Gerry.
Thanks again for all your replies, I'll take another read through tomorrow and reply properly. Nothing much else to do during this lockdown anyway.
Stay safe people and thanks again, all your help is very much appreciated!
