If we take Paul literally and seriously, Jesus had a brother named James.
Galatians 1
18 Then after three years, I went up to Jerusalem to get acquainted with Cephas[b] and stayed with him fifteen days. 19 I saw none of the other apostles—only James, the Lord’s brother. 20 I assure you before God that what I am writing you is no lie.
