In the fifth century there lived in Brecknock an Irish invader, Brychan by name, who died in 450. According to Welsh accounts, he had twenty-four sons and twenty-five daughters, in all forty-nine children. Statements, however, vary, of which this is the largest. The smallest number attributed to him is twenty-four; and, as his grandchildren may have been included in the longer list, this may account for the discrepancy. He is said to have had three wives—Ewrbrawst, Rhybrawst and Peresgri—though it is not said that they were living at the same time. The fact seems to have been that all the Hy Brychan or family are regarded as brothers and sisters. The names of the sons and daughters and grandchildren of Brychan are given in the _Cognacio Brychani_, and in the Bonnedd-y-Saint; and a critical examination of the lists is given by Dr. Rees in his _Essay on the Welsh Saints_. In the “Young Woman’s Window” at St. Neots, near Liskeard, in Cornwall, is fifteenth-century glass, which represents Brychan with his offspring, twenty-four in number, all of whom have been confessors or martyrs in Devon and Cornwall. The following are named: 1. St. John, or Ive, who gave his name to the Church of St. Ive; 2. Endelient, who gave his name to Endelion; 3. Menfre, to St. Miniver; 4. Teth, to St. Teath; 5. Mabina, to St. Mabyn; 6. Merewenna, to Marham Church near Bude; 7. Wenna, to St. Wenn; 8. Yse, to St. Issey; 9. Morwenna, to Morwenstow; 10. Cleder, to St. Clether; 11. Kerie, to Egloskerry; 12. Helic, to Egloshayle; 13. Adwen, to Advent; 14. Lanent, to Lelant. Leland, in his _Itinerary_, adds Nectan, Dilic, Wensenna, Wessen, Juliana,[4] Wymp, Wenheder, Jona, Kananc, and Kerhender. A few, but not many of these can be identified with those attributed to Brychan by the Welsh genealogists. Morwenna is most probably the Welsh Mwynen, in Latin Monyina, daughter of Brynach Wyddel by Corth, one of the daughters of Brychan; and her sisters Gwennan and Gwenlliu are probably the Wenna and Wenheder of Leland’s list. St. Morwenna was therefore apparently the granddaughter of Brychan. Her father, Brynach Wyddel, is the St. Branock of Braunton near Ilfracombe. He also founded churches in Carmarthen and Pembroke.
