Tomas ap Rhodri

Tomas ap Rhodri, or Thomas Rothery (c. 1300–c. 1363), was the only son of Rhodri ap Gruffudd, youngest brother of the Welsh princes Llywelyn and Dafydd ap Gruffudd. He inherited his father's estates in Cheshire and Surrey, later exchanging the Cheshire lands for holdings in Gloucestershire and Powys.

As Owain Goch's closest male heir he made an unsuccessful claim to the lordship of Llŷn. By his wife Cecilia he fathered Owain Lawgoch, who proclaimed himself Prince of Wales in 1369.
