Mary, I am hoping you are still active in your research into the Powell family of Castle Madoc. I have traced my ancestry back to William, Hugh and Hugh Powell -- via Ancestry.com. Much of this came from other family trees, but the birth and death dates, as well as marriage and birth records seem to confirm what I have traced.
Just recently having completed a branch of my ancestry to the Powells of Castle Madoc, I confess really a novice. However on your post you offered to email information you have on the Powells. I would so much appreciate having it.
I am Judith Andrews email: judy@andrews.net
and I live in Dallas, Texas, USA.
