Being Rh Negative implies that you do not have the Rh antibodies in your blood and the genes that are responsible for the formation of the antibodies. If both the Mother and the Father is negative and do not have the genes the baby can only be negative.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
