These appear to have been the last of the Physicians who practised at Myddfai. The above John Jones resided for some time at Llandovery, and was a very eminent surgeon. One of his descendants, named John Lewis, lived at Cwmbran, Myddfai, at which place his great-grandson, Mr. John Jones, now resides.
“Dr. Morgan Owen, Bishop of Llandaff, who died at Glasallt, parish of Myddfai, in 1645, was a descendant of the Meddygon, and an inheritor of much of their landed property in that parish, the bulk of which he bequeathed to his nephew, Morgan Owen, who died in 1667, and was succeeded by his son Henry Owen; and at the decease of the last of whose descendants, Roberts Lewis, Esqr., the estates became, through the will of one of the family, the property of the late D. A. S. Davies, Esqr., M.P., for Carmarthenshire.
“Bishop Owen bequeathed to another nephew, Morgan ap Rees, son of Rees ap John, a descendant of the Meddygon, the farm of Rhyblid, and some other property.
“Amongst other families who claim descent from the Physicians were the Bowens of Cwmydw, Myddfai, and Jones of Dollgarreg and Penrhock, in the same parish; the latter of whom are represented by Charles Bishop, of Dollgarreg, Esqr., Clerk of the Peace for Carmarthenshire, and Thomas Bishop, of Brecon, Esqr.
“Rees Williams, of Myddfai, is recorded as one of the Meddygon. His great grandson was the late Rice Williams, M.D., of Aberystwyth, who died May l6th, 1842, aged 85, and appears to have been the last, although not the least eminent of the Physicians descended from the mysterious Lady of Llyn y Fan.”
Sir John Rhys mentions of another Dr. Williams also a descendant of the Lady of Llyn y Fan, who was living at Aberystwyth in 1881.
It seems that there are several families in different parts of Wales who are said to have fairy blood coursing through their veins; and the noble Lady Bulkeley, who lived in North Wales, three or four generations was supposed to be descended from a Fairy lady who married a mortal.
There is also a tradition that after the disappearance of the lady the disconsolate husband and his friends set to work to drain the lake in order to get at her, if possible; but as they were making a cutting into the bank a huge monster emerged from the water and threatened to drown the town of Brecon for disturbing him, saying:—
