|SOME NOTES ON MEDIEVAL ENGLISH GENEALOGY|
Volume 12, part 1, page 459 (as corrected in volume 14):
After this [a declaration that a previous marriage had been void, about 1507] he [Charles Brandon, later Duke of Suffolk (d.1545)] m., about 1508, in full Court, the abovenamed Anne, 3rd da. of Sir Anthony BROWNE, K.G., by his 1st wife.(ax)
Her identity is unknown ...
Sir Anthony's first wife was perhaps the Eleanor Ughtred, for whose marriage to Sir Anthony Brown, knight, a licence was issued to the rector of St Wifrid's, York, 20 January 1487/8 [Testamenta Eboracensia (Surtees Society, vol.45, 1865), vol.3, p.352]. Complete Peerage, vol.12, part 2, p.164, note c, says that this Eleanor was the daughter of Sir Robert Ughtred (d.1487).
[Adrian Channing suggested this identification for Anne's mother, in November 2001.]
