Maryland was originally intended to be called "Crescentia": Lord Baltimore's original plan was to name the colony after the Queen Henrietta Maria, the wife of King Charles I. However, the name was already taken, so he proposed the name "Crescentia" instead. The name was eventually changed to "Maryland" in honor of Henrietta Maria.
