An English song of ten stanzas in the Welsh metre known as tri-thrawiad is to be found in N.L.W. MS. 14402 , a manuscript book in the hand of Humphrey Jones of Castle Caereinion (b. 1719 ), which contains, together with other matter, a number of songs by poets of the Meifod and Caereinion districts. The song already mentioned bears the title ‘ A Christmas Carol, 1783, o waith fy hen feistr ,’ and it is followed by the note: ‘Yr hen Siôn Abel a'i canodd’ (‘by old Siôn Abel’). It may be presumed that Siôn Abel , the master , did not dwell far from the home of his pupil, Humphrey Jones of Caereinion .
