Tomas ap Rhodri

Tomas ap Rhodri or Thomas Rothery was the only known son of Rhodri ap Gruffudd, the youngest son of Prince Gruffydd ap Llywelyn Fawr and younger brother to both Llywelyn ap Gruffudd and Dafydd ap Gruffydd. After the deaths of Llywelyn, Dafydd, and their eldest brother Owain the Red between 1282 and 1283, Rhodri became the most senior member of the Aberffraw Dynasty to retain his liberty because he had sold his rights of succession to his brother Llywelyn around 1270 before he had had any children of his own. Tomas did not make any claim himself to the throne of Gwynedd.
