Thanks. Either that or speak to his Gran to see if she can remember if her mum had any brother or sisters or even if she heard of her grandparents names. Bit of a challenge as Hannah's daughter was only about 3 when Hannah died
Now that sounds a better course, I hope at least her siblings and where they came from would give a guide, but failing that I'm sorry, the marriage cert is the only route, but with so many potential Hannah Jones with father ie George, a very dificult challenge!
See what you can find out, but believe me I do feel sorry for you, as on my Welsh side, it was a nightmare!
