The source behind the name

USGS GNIS Populated Place names in all 50 states and DC. Features in the historical extract or explicitly named historical are excluded; duplicate decision records with identical identities and coordinates are collapsed. GNIS points identify names, not legal or neighborhood boundaries, current occupancy, school attendance or a statistical population. Nearby Census places and tracts remain separately named geographies. Name completeness and currency vary; this is not a claim to include every locally used neighborhood name.

USGS description & history

Located along the Patapsco River, about 37 km (23 mi) north northwest of Annapolis.

Laid out in 1729 on the lands of Thomas Carroll and was named to honor Cecil Calvert, the second Lord Baltimore, and proprietor of Maryland. Cecil's father, George Calvert, had become Lord Baltimore, of the Barony of Baltimore in Ireland in 1625. Records indicate that the Irish Lord took the name Baltimore from a seaport in County Cork, as was tradition for titles and baronies to be named after local ports. The Gaelic elements are "bailte" and "mora", which mean "big houses, homesteads, estates." In 1745 the growing community of Baltimore absorbed nearby Jones Town (or Oldtown). A popular nickname for Baltimore is "Charm City." Today Baltimore is ranked 17th largest city by population in the United States. (US-T121)
