According to legend “a dragon flourished on the land of Sir Ralph Maelog, lord of Cibwr and made a great part of it desolate, destroying men and beasts”. In keeping within the story, an English adventurer came by, Sir Gwrgy Grant, and slew the dragon somewhere above Pen-y-lan Hill and Sir Ralph Maelog bestowed upon him the hand of one of his daughters and co-heiresses whence sprang the family of “Grant” of Llwyn-y-Grant, which very soon abandoned their English surname in favour of the Welsh patronymic nomenclature.
