That link is great Daisy, I'll give it a good read.
Thanks also Dakkobear. This line of the family are from Denbighshire in N.Wales, mainly farming folk I think, and all called John or Ellen Williams it seems! The problem I will have is that most of the graves and records are going to be in welsh, and my welsh is pretty rusty to say the least! Though I got the jist of what was on the gravestone at the W/E my father came to the rescue with a full translation.
I'm really excited to get started now!
