Hi Jean
Will have to check out the Vaughan connection later. There are so many in the area it's difficult to untangle them all and it's a part of the family I've not done much work on.
I thought I'd just make a quick check on photos I took last year when attending a family wedding in Llangedwin. I live quite a long way from there and, of course, couldn't miss the opportunity to take photos of any graves I thought I might have a connection with to work on later. (Everyone else was taking photos of the bride, groom and guests whilst I was hopping about the graveyard in all my wedding gear frantically photoing graves!!
Anyway, I have a photo of the grave of a William Vaughan of Cil Bach if you're interested. The year of death is a bit difficult to make out but it looks like 1861 aged 66yrs. Let me know if you want this.......
Best wishes
Jane
