The surname Yale is derived from the Welsh word "iâl", meaning fertile ground, which was the name of the lordship of Yale in Wales of the royal house of Mathrafal. The name was later given to the estate of Plas-yn-Iâl by the House of Yale (Yale family), a cadet branch of Mathrafal through the princes of Powys Fadog and Fitzgeralds of Corsygedol.

Arms of Baron Ellis ap Griffith, heir by marriage of Plas-yn-Yale, founder of the House of Yale[1][2]
