My dad knew a girl named MerryChristmas; given name Merry, surname Christmas...No, I am NOT joking!!!Merry = happy or joyous; cheerful, etc. Almost archaic. Christmas = Christ-mass, Christ from Greek 'Christos', savior; and the Catholic mass.
I once bought a house...through a real estate agent named MaryChristmas. And she acquired the surname by marrying one GlennChristmas (common last name in those parts). Now, THAT'S love!
