Mary, and Joseph had to go to the city of David to register by the Roman Emperor so they went..Joseph was from the lineage of the House of David. Hundreds went with them it was a census. The city was noisy so Joseph chose a quiet spot for Mary to rest. The story said it was a stable We can ask when we get to heaven. They were not immigrants so that tale is blown out of the water. That had to bring the child to the temple on the 8th day for Jewish introductions. Remember Elizabeth was married to a priest so it could have been him. The family may have stayed with them after the birth. Back they went home where Joseph had his carpenter shop. No immigrants just a fallacy by left wing kooks.Mary was from the House of David as well. Beloud
