Rees

Rees is a name of Welsh origin, derived from the Welsh word "rhi" which means "lord". The name has been associated with prominent figures in Wales throughout history. One such figure was Rhodri Mawr (Rhodri the Great), who ruled over Gwynedd in the late ninth century and early tenth century. He had a son named Cadwallon ap Rhodri, whose name is derived from "Cad" meaning "battle" and "wallon" meaning "leader". Although Rees was not his actual name, it has been suggested that it may have been used as a diminutive form of Cadwallon.
