I think I may have found one of the parents of Mary Edwards(nee Jones) and Robert Jones,but it has thrown up another query that raises some doubt as follows:
There is an 1808 will at NLW for Robert Jones of Groesvaun(sic),Llansantffraid Glyndyfrdwy,who as well as having the same(?) address as Mary Edwards(1761-1843),has children Robert,John and Jane(as well as Mary) to match the siblings in Mary's will.
Mary's husband William Edward's(1762-1839) will specifies nieces:-
Mary Jones Plas Newydd Corwen
Elizabeth Hughes Ty Mawr Corwen
These,I think, are the married daughters of John(1753-1846) and Jane(1757-1849) Edwards,who have other children
Edward Edwards Llwyn y Brain
Jane Edwards Fedw
Margaret Jones (nee Edwards) Fedw
These also match the children specified for Mary's sister Jane leading to a possible conclusion that sisters Mary and Jane married brothers William and John.
However,I can't find an appropriate marriage for John Edwards and Jane Jones.There is a marriage that looks exactly right for place and time-1782,Llansantffraid Glyndyfrdwy but it is with a Jane Roberts(William Edwards and John Roberts witnesses)It could be a second marriage for Jane,but I can't find a first,and the name of the second witness could be significant.
Any comments welcome
Regards
Roger
