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

Settlement occurred prior to 1790 and the name Dormont was suggested by Gilbert M Brown, the first burgess of the community, who named the site for the surrounding picturesque and rolling hills, and the bountiful opportunities which the area offered. (PA-T169/p197)
