I did some research for a friend and came across some of the important families around Ruthin, Cefn Coch rang a bell but it was much later than this.
This hasn`t solved the problem with Thomas Lewis and his family, but it shows that he was employed by a good family. Also that Price Jones moved around, ended up close to Llangollen, presumably died in Wrexham and was buried in Llanychan.
