Title: Gwladys
Content:  The medieval lives of Cadoc (by Lifris c. 1086) and of Gwynllyw (c. 1120) preserve different legendary details of Gwladys. Among the best attested of all of Brychan's half-Irish saintly children, she is also mentioned in Welsh king-lists. Both saint's lives agree that Gwladys, daughter of Brychan married Gwynllyw and gave birth to Cadoc. In the Life of Saint Gwynllyw, the king is just and fair and the marriage is accomplished peacefully, while the tale of Glwadys' marriage in Lifris' work seems similar to abduction stories in other saints' lives as well as in other Arthurian stories, indicating that it is myth rather than history. Here, when her father refused to allow their marriage Gwynllyw

Title: Glywys
Content:  Glywys is a legendary early 5th century Welsh king, an important character in early Welsh genealogies as the eponymous founder king of Glywysing, a southeast Welsh kingdom whose heartland lay between the Tawe and the Usk. In one genealogy Glywys is reckoned the eldest son of Solor, son of Mor.

Various claims were made for Gerald's antecedents: that his father or his grandfather was a Saxon or Florentine baron; that his mother was one Gwladys ferch Ryall, or "princess" Gwladys ferch Gruffydd of Gwynedd, or "princess" Gwladys ferch Rhiwallon ap Cynfyn of Powys; that Gerald's grandfather was one "Dominus Otherus", a Tuscan nobleman descended from a Duke of Florence named Cosmo or Cosimo/Cosimus "Gherardini". The foregoing claims are erroneous. Pursuant to Domesday, Gerald's mother was Beatrice, not Gwladys ferch Gruffydd or Gwladys ferch Rhiwallon; the latter, in fact, was Gerald's mother-in-law. It's unlikely the Conqueror would have granted Walter lands in Berkshire, Buckinghamshire,
