Who were the mortal brothers of Jesus Christ, and did He have any mortal sisters?
Here's answer to week's question
After the birth of Jesus Christ, His mother, Mary, and her husband, Joseph, had four sons, James, Joses, Simon and Judas. Matt. 13:56 shows He had sisters. "The number of girls is not specified, but the Greek text makes it clear that there were more than two. Since the exact number is not known, this is presented in the KJV as `all his sisters.' "
