Roger,
Thank you for this information! The mention of Llechwedd is quite interesting and may provide a link to the below:
Thomas Jones (clerk) was buried in Llandrillo, I know from his will, and the only likely gravestone from the memorial inscriptions booklet is among a cluster of graves for other similar Joneses, one of whom is for 'Giles Jones, the son of John Jones, Llechwedd', d.1801 aged 25. This is interesting as Thomas Jones (clerk)'s son was 'Edward Giles Jones'. The above gravestone also records 'Elizabeth Foulkes' (1732-1752), who (according to parish records) was the daughter of Thomas Foulkes, Dinan d. 1736 (who shares a gravestone with 'John Jones, Tyddyn y Merched (Llechwedd), Gent.' (1760-1829 - father of Giles?).
If Thomas (clerk) was born in Llandrillo, the only likely record is as the son of Foulke Jones (b. 1739), who in turn was the son of Thomas Jones (1676-1748) and Elizabeth Foulkes. This Thomas appears to be the son of John Jones (d.1705, Llandrillo) and Gwen.
On the grocer line, if you remember in a previous post I had asked about the will of William Jones, grocer of Corwen (d. 1774, Corwen). William's nephew is Rowland Jones (d.1782), the parish clerk of Corwen before Thomas - (Thomas' son, John Jones, succeeded him as parish clerk of Corwen, so it would make sense if his predecessor, Rowland Jones, was also a relation). William Jones also had another cousin, Griffith Jones. A Griffith Jones (d.1770, Corwen), is shown as living at Plas Adda (which is the house in which Thomas Jones, Clerk, lived). I'm pretty sure they all must be related in some way, along with the grocers of Llanfyllin who seem to have received Moelyskedwi, the difficulty is trying to piece together how they're related!
Thanks,
Jones9
