Gabriel in the Old Testament
Mary's angel Gabriel is also the angel who appeared to Daniel in the Old Testament (cf. Daniel 8,9)
Gabriel in the Hail Mary
It is also worth noting that the archangel Gabriel's words to Mary form the beginning of the Hail Mary prayer:
Haile thou that art highly favored, the Lord is with thee: Blessed art thou among women. Luke 1:28 KJV
In the Hail Mary, Elizabeth's greeting then complements Gabriel's greeting, i.e.
Blessed art thou among women, and blessed is the fruite of thy wombe. Luke 1:42 KJV
Gabriel's Feast Day
The feast day of Gabriel, along with Raphael and Michael (the only other angels identified by name in Scripture), is celebrated on September 29th, commonly referred to as Michaelmas Day. (cf. Thurston & Attwater 1956, p.677)

Joseph and Mary were betrothed to each other. Joseph had to go to Bethlehem to be registered because he was an ancestor of King David. Mary, who was with child went with him.
