Who may have been Jude half brother?

Jude, traditionally identified as a half-brother of Jesus, is believed to be one of the sons of Mary and Joseph. This makes him a member of Jesus' immediate family. In the New Testament, he is mentioned in the Book of Jude, where he identifies himself as "a servant of Jesus Christ and a brother of James." This James is often considered to be another brother of Jesus, further supporting the belief that Jude is also a half-brother.
