Joseph is the patron saint of the Universal Church, families, fathers, expectant mothers (pregnant women), travelers, immigrants, house sellers and buyers, craftsmen, engineers, and working people in general.
We know Joseph was a compassionate, caring man. When he discovered Mary was pregnant after they had been betrothed, he knew the child was not his but was as yet unaware that she was carrying the Son of God. He knew women accused of adultery could be stoned to death, so he resolved to send her away quietly to not expose her to shame or cruelty. However, when an angel came to Joseph in a dream and told him, 20 "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. 21 She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins," he did as the angel told him and took Mary as his wife. (Matthew 1:19-25).
