From the Old Welsh name Matauc, derived from mad meaning "good, fortunate" combined with a diminutive suffix. This is the name of a warrior mentioned in the 7th-century Welsh poem Y Gododdin. It was also borne by several medieval rulers, including the 12th-century Madoc ap Maredudd, the last prince of Powys.
