Hi Cousin Ben
I have sent you a pm message.. i have found out loads!!!!. I have sent you the link to the website i have set up to put it all in the same place... maybe with a few heads together we can find out more.
William Thomas dad was Richard Thomas, the mistake i was making was i was looking for William still in Wales until he was an adult, i have since found out his mum and dad moved to Bilston when William was a young boy, his mum was called Mary, but she died and Richard boarded with Sarah Cullis before marrying her. Richard had children with Sarah. From what i can see he stayed in Bilston area but the rest of the family moved to Pendlebury to mine up here.
Have a look at the site and see if what i have found out so far matched with what you have found out....
I have been in touch with Auntie B and S, I have brought them up to speed on what i have found out and given them the link to the website.
