As Abraham wife Sarah was baron Ishmael was then born through Hagger the slave .
Additional Answer:
Hagar was more than just the female handmaid or as you put it "slave" of Sarah, she is historically known to be an Egyptain princess and daughter of a pharaoh. Please take note of the following:-)
-In Rabbinical Literature:
According to the Midrash (Gen. R. xlv.), Hagar was the daughter of Pharaoh, who, seeing what great miracles God had done for Sarah's sake (Gen. xii. 17), said: "It is better for Hagar to be a slave in Sarah's house than mistress in her own."
_ It is then clear from this Rabbinical Literature that Princess Hagar was of a Kingly line and not just of any one as to say" a slave," but of a Pharaoh father, king of Egypt! It must also mean that her son Ismael must have gone on to become a king in his own right, for the scripture clearly says he begot twelve princes and goes on to name each prince.
Ishmael was the oldestg son born to Abraham and Hagar, Sarah's servant (Genesis 17). The name means, literally, "God hears him," and is a response to the little boy's cry in the wilderness after he and his mother had been driven away by Sarah.
Ishmael is the son of Abraham (then known as Abram) and Hagar. The name Ishmael means God hears.
