Baron, or Lord, Baltimore is a now extinct title of nobility in the Peerage of Ireland. Baltimore is an Anglicization of the Irish phrase "baile an thí mhóir e," which means "town of the big house."
The title was first created for Sir George Calvert in 1624. The title became extinct in 1771 after the death of the 6th Baron. Sir George and his son, Cecil Calvert, were British subjects rewarded with land in the new world.
