Meghan, 37, and Harry, 34, stepped out with their newborn son at St. George’s Hall in Windsor Castle, where they had their wedding reception last May.

The couple did not choose an aristocratic title for the baby, who is not a prince but could have been given a title with "Lord" before his first name. The couple did not disclose why they had chosen the names — though the meaning of Harrison, "son of Harry," could be a clue.

After Archie Harrison was born on Monday morning, a beaming Harry, told reporters, "The baby is a little bit overdue so we've had a little bit of time to think about it. That's the next bit."
