there is no status of actual marriage between Jews and Gentiles- The true identity of a child as a Jew or a Gentile by birth is matrilineal; it follows the identity of the mother who conceived the embryo and carried it through pregnancy until the child's birth. This is stated explicitly by God in the Torah (see Rashi on Deuteronomy 7:4). On the other hand, the membership of a born- Jewish person in one of the Twelve Tribes of Israael is patrilineal, based on the tribe of the born-Jewish father. Therefore, a child who is born to a Jewish woman and a Gentile father is fully Jewish, but without membership in any of the Twelve Tribes; see Rashi on Leviticus 24:10. (the Divine Code by Rabbi Moshe Weiner, Ask Noah International, 2011, p 509).
