"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:-- "Os na cha'i lonydd yn fy lle Mi fodda, dre Byrhonddu!" (If I get no quiet in my place I shall drown the town of Brecon). so they had to give up draining the lake. There are extant several versions of the Myddfai Legend. In the "Cambro Briton" Vol. II., pages 313-315, we have a version in which it is stated that the farmer used to go near the lake and see some lambs he had bought at a fair, and that wherever he so went three most beautiful maidens appeared to him from the lake. But whenever he tried to catch them they ran away into the lake, saying:-- "Cras dy fara, Anhawdd ein dala." (For thee who eatest baked bread It is difficult to catch us.) But one day a piece of moist bread came floating ashore, which he ate, and the next day he had a chat with the maidens. After a little conversation he proposed marriage to one of them, to which she consented, provided he could distinguish her from her sisters the day after. Then the story goes on very similar to Mr. Rees' version which I have already given in full.
