"Where were these br(o)thers and sisters when Mary and Joseph went to Bethlehem?"

Good point. Also, if Joseph was so concerned of himself that he contemplated putting Mary aside for being "with child" and unwed, it hardly makes sense he should himself father children out of wedlock, so these "others" could not have been younger siblings from other spouses.

I have read that many Catholics believe Joseph was a widower and that he brought children into the marriage..but that would make them all the big brothers and sisters with Jesus being the youngest..it also begs the question where were these "kids" when the Holy couple traveled and later settled in Egypt

One more thought..It is a sin for a woman to refuse to be a wife in all respects to her husband...so if Mary refused that right to Joseph that was a sin..

Now in the long runs none of this matters much ..Jesus is still the product of a Virgin Birth , Son of God..King of Kings and Lord of Lords..
