Angharad ferch Llywelyn
Angharad ferch Llywelyn (fl. 1260) was a daughter of Llywelyn ab Iorwerth, Prince of Wales. The identity of her mother is uncertain; but several later genealogical sources give Llywelyn's consort Joan as her mother. She is almost absent from contemporary records, however she is mentioned in a document dated 1260, the year of her death and in sources recorded as married to Maelgwn Fychan.
