. The duke remains sixth in line to the throne -- albeit without a royal title
, but he could still move further down the line if the family expands. Harry follows his father, Prince Charles; his older brother, Prince William; and William's three children with Catherine, the Duchess of Cambridge.
Harry's son with Meghan, Archie Harrison Mountbatten-Windsor, remains in seventh place, and the couple's new baby daughter, Lilibet "Lili" Diana, is now eighth in the line of succession.
