'Family' in the Bible

And Saul answered and said, Am not I a Benjaminite, of the smallest of the tribes of Israel, and my family the least of all the families of the tribe of Benjamin? and why dost thou speak such words to me?

And he caused the tribe of Benjamin to come near by their families, and the family of Matri was taken; and Saul the son of Kish was taken. And they sought him, but he was not to be found.

And David said to Saul, Who am I? and what is my life, or my father's family in Israel, that I should be son-in-law to the king?

If thy father should actually miss me, then say, David earnestly asked leave of me that he might run to Bethlehem his city; for there is a yearly sacrifice there for all the family.

and said, Let me go, I pray thee; for we have a family sacrifice in the city; and my brother himself has commanded me to be there; and now, if I have found favour in thy sight, let me go away, I pray thee, and see my brethren. He has therefore not come to the king's table.
