I have also been looking for David Buftons. My earliest one was the miller at Llanyre, Radnorshire (1806-37). I know he was buried at Nantmel, but do not know his family further back. In my research, I have come across a lot of Buftons in the area including quite a few Davids, also Benjamin. If you haven't tried the National Library of Wales' website I recomend you do. They have wills and other records free to view online. Benjamin Bufton's will is there along with various other Buftons. My problem is that I don't know how they are all connected. If you can help me please get in touch!
