Borrowed from French Mascon, from Medieval Latin Masconis, a syncopated form of Madasconis and Matisco, probably from Gaulish matus (“bear”) (from Proto-Celtic *matus, commonly understood as a euphemistic derivation from *matis (“good”)) and a suffix equivalent to -iscus (“-ish: forming adjectives”).
