WRJ,
There's also a John Jones baptised 12 Sept 1780, son of John and Mary of Cwm, Carrog. In addition to the one I mentioned in 1781 (who I now think actually died in infancy also!), there's a John Jones baptised 4 Nov 1781 son of Richard and Catherine, (just) of Corwen. Carrog definitely is quite towards Glyndyfrydwy so perhaps this one is more likely? There aren't any convincing marriages in Corwen, the closest is between John Jones and Magdalen Thomas in 1797. Also in 1797 is John Jones and Margaret Beans, although I don't suppose either of them are particularly likely! There are quite a few on familysearch - a possible one in Wrexham 1797?
I've found another will now of Thomas Jones of Plas Newydd, Carrog, d.1829 - he had a son Thomas and there is an Edward Jones as a witness. There's a grandchild, Thomas Jones (son of John) who I notice from the 1851 census (if same family) was born ca.1820. I can't find a burial in Corwen however so perhaps it was in Carrog. Can anyone find his burial record for age at death? Would he have been born early enough for his son Thomas Jones to be born around 1776? I know this one's maybe unlikely again but a death in the 1820s would seem logical as their son returned for a brief period around that point.
There's also a will for Margaret Jones d.1826 Pen y Bryn, Mwstwr, Corwen - an apparent burial at this time suggests she was born ca.1745, so this could be possible also! If anyone can find her husband it would be a great help - can't find any other wills at Pen y Bryn except for Edward her son, I'd imagine. I'm trying to see if there's a Thomas Jones connected to this farm who might be her husband.
