Margaret Powel born in Vaynor circa 1798. Her father was David Powel. Margaret married William Williams of Merthyr Tydfil in Vaynor on 12 Nov 1817 spending most of her married life in Merthyr.
It is possible that David Powel married Jennet David on 4th July 1796 again in Vaynor but I cannot make a definite link with Margaret.
Any information gratefully received.
