Meaning: “courageous ruler.”
The name is derived from the Old Germanic elements merri (courage) and rik (ruler). It was borne by an 8th-century French saint.
The name is considered rather archaic in France but has always been rather common among the francophones of Canada. It has been borne by several Canadian politicians, the most famous being Médéric Martin (1869-1946), the 32nd mayor of Montreal.
Currently, it is the 308th most popular male name in Quebec, Canada (2010).
Other obscure French forms are Méry and Merri.
