"Der" in the last name of Armenians means the person is descended from a kahanah–married priest (Der-Der). "Mghts" in the last name of Armenians (ex: Mghts-Artinian) means the bearer’s ancestor had made a pilgrimage to the Holy Land. "Mghts" is short for "Mkadas"–holy in Arabic. These days some North American Armenians spell "Mghts" as "Mix."
