Following the failure of the Avalon Colony, Cecil Calvert oversaw a second colonial enterprise in 1633, this time aimed at the Chesapeake Bay area, north of the colony of Virginia. The new colony was named "Maryland" after Henrietta Maria, the French-born consort of King Charles I. Anne Arundel County, Maryland was named after her.
