Jesus had four half-brothers (their father was Joseph and Mary was their mother) - James, Joses, Simon, and Judas – and two or more un-named half-sisters.
Matthew 13:55 Is not this the carpenter’s son? is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas? 56 And his sisters, are they not all with us?
I hope you find this helpful.
