Did Jesus have brothers or sisters? Did Mary and Joseph have other children after Jesus birth?

Answer:

Yes, Jesus did half half brothers and sisters (since they only shared the mother, Jesus father was not Joseph)

Here is where it is found…

Matthew 13:55-56  Is not this the carpenter’s son? is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas? And his sisters, are they not all with us? Whence then hath this man all these things?
