Well, if they do, I didn't get much further with her. She was born Gwyddelwern 1805 - parents were Margaret Edwards and Robert Jones and then they disappear into the mists of time.
My Margaret's 3rd daughter was Martha - my great grandmother 
Have just looked at Gwyddelwern on Google earth.... gosh its only one road!!
When we found out that Robert and Martha had the Eagles Inn in Corwen we went and had a drink there. If I'd known Robert only come from 'up the road' we'd have stopped off there too!

Whereabouts is Llanfawr?
My Martha is my Gt Gt Gt grandmother!!!
