If you're talking about the figures in the Biblical book of Genesis, then let's back up a few generations and try to get it straight: -- Abraham migrated to Israel late in his life. His children included his son Isaac. -- Isaac lived his whole life in Israel. His children included his son Jacob. -- Jacob left Israel, worked for his uncle for 20 years, and returned to Israel. He had 12 sons and one daughter. Joseph was one of the sons. Dina was the daughter. Joseph was forcibly taken to Egypt as a teen-ager. Years later, Jacob and the rest of his family migrated to Egypt during a famine. All of them died there. Their descendants left to return to Israel only after another 230 years, and only a few of them completed the return trip. -- Joseph had two sons: Ephraim and Menassah. There were no daughters. The sons were born, lived, and died in Egypt.
According to the Torah/Genesis, Abraham had sons by both his wife Sarah, and by Sarah's handmaiden, Hagar. Isaac was the son born of the former, Ishmael the son born of the latter. The Ishmalites are the descendants of Ishmael. "Ishmalite" is also generally taken to be another word for "Muslim".
In the final plague in ancient Egypt, all the firstborn sons of the Egyptians were killed, while the Israelite firstborn sons were spared by following instructions to mark their doorposts with the blood of a sacrificial lamb.
