Llywelyn ap Gruffydd (Llywelyn the Last) was killed on 11 December 1282 in a minor skirmish at a bridge on the River Irfon. Stephen Frankton was the English soldier who struck him down, probably unaware of his identity at the time. Subsequently, he was decapitated and his head sent to the victorious Edward I at Rhuddlan. The circumstances of how he got to be so far from the main battle are still mysterious. There can be no true descendants of Llywelyn ap Gruffydd. He was nearly 60 when his future wife Eleanor de Montfort was released from captivity by Edward I so that they could marry. Eleanor died in childbirth when their only child, a daughter Gwenllian, was born. After Llywelyn's death Gwenllian spent her life in the Gilbertine convent at Sempringham, Lincs. There does not appear to be any mention of illegitimate children fathered by Llywelyn ap Gruffydd (as opposed to those of his grandfather, Llywelyn ap Iorwerth "the Great", amongst whose descendants are Elizabeth II).
