There are two Davies in the Caron List ... William Davies of Wernfelen and his son, Thomas Davies, living at, and with a Freehold at Ystrad.
I see that the Freehold of Pantycamddwr is held by David of Ffos. (this links to the "Pew" indent), and that Penbryn is the home of David Richards but that he owns the Freehold of Ynys y Garn.
Llwynykedni is so familiar but I can't locate it.
I can feel a stinker of a cold heading my way so forgive any ridiculous mistakes that I may make over the next few days.
I also see the expenditure, from 1746, for repairs and materials to Ynys y Garn, paid by Crosswood.
