Family name origins & meanings
- American : apparently from the city in MD or from the title of the English Barons Baltimore, borne by members of the Calvert family, who were Lords Proprietors of the colony of MD in the 17th century and for whom the state capital was named. As a family name, Baltimore seems to have originated in America (appearing in VA in the 1660s). There is no record of any Calvert descendants having assumed the title as a surname.
