Skoosh.
Thanks, Skoosh. I've added it to my wishlist. it might give me some helpful background to a branch of my tree that I've come to a dead halt with.
I've been looking at my 6x great grandfather Thomas Dodd, trying to figure out his birth and birthplace. He would have been born about 1690. He married and had his children in Askham, near Penrith but I can get no further back than that.
A while ago, I became aware that the surname DODD(S) was one of the Reivers family names, centred around Bellingham near Hexham. There's no sign of Thomas being baptised in the Askham area. I did attempt to find out if there was any link - right area of the country, though Penrith and Hexham are quite a few miles apart.
His daughter - my 3x gg - had a child by a William TODD in Askham in 1734, and I believe TODD is another reiver surname.
