'Sons in law' in the Bible

Then the men said to Lot, Are there any others of your family here? sons-in-law or sons or daughters, take them all out of this place;

And Lot went out and said to his sons-in-law, who were married to his daughters, Come, let us go out of this place, for the Lord is about to send destruction on the town. But his sons-in-law did not take him seriously.
