According to Charles W. Bardsley, this name refers to the Virgin Mary and her mother Anna: "Speaking of Mary’s husband, we may add that two of the most familiar conjunctions of the present day among the middle and lower classes, that of Anna Maria or Mary Ann, arose similarly. In Italy and France the two went together a hundred years earlier, in connection with the Virgin and her mother. In England they are only found since 1700, being used as commemorative of the sisters Anne and Mary, both queens. Like William Henry, the combination has been popular ever since" (Curiosities of Puritan Nomenclature (1880), pages 220-221).
