'Family' in the Bible

When Jehu came to Samaria, he killed everyone who remained of Ahab’s family in Samaria, until he had destroyed all of them, in accordance with the word of the Lord which He spoke to Elijah.

But in the seventh month Ishmael the son of Nethaniah, the son of Elishama, of the royal family [who had a claim to be governor], came with ten men and struck and killed Gedaliah and the Jews and the Chaldeans who were with him at Mizpah.
