Really grateful to MP Giffiths and Paul. Between your contributions I now have somewhere 'to go'.
The only thing I still don't know is the whereabouts of Lydley. Because of help received hee this has changed from being required informationto something that is just bugging me because I've never before failed to find a place I was looking for.
All I can offer in return is that I am researching the Pontesbury branch of the Ashtons of Trefeglwys, Montgomeryshire of which William Ashton Butt is a member.
If I can help in any way contact me here or via the Powys network

Regards

Sam
