A Madonna is a representation of Mary, either alone or with her child Jesus. These images are central icons for both the Catholic and Orthodox churches. The word is from Italian ma donna 'my lady'. The Madonna and Child type is very prevalent in Christian iconography, divided into many traditional sub-types especially in Eastern Orthodox iconography. Source
Joseph was a 1st-century man of Nazareth who, according to the canonical Gospels, was married to Mary, the mother of Jesus, and was the legal father of Jesus. The Gospels also name some brothers of Jesus, who may also have been Joseph's sons; the Gospel of James, an apocryphal work of the late 2nd century, theorized these as the sons of Joseph from an earlier marriage. This position is still held in the Orthodox churches, but the Western church holds to Jerome's argument that both Joseph and Mary must have been lifelong virgins and that the "brothers" must have been his cousins.
