Hartline
An English-language surname most likely built from the word hart, “deer,” plus a topographic or place-name element.
The #9,050 most common surname in the United States (2010 Census) — about 1 in every 85,525 Americans shares it.
Etymology
Hartline is most plausibly an English surname formed from hart, an old word for a male deer, and line, a element that in surnames can reflect a boundary, lane, or strip of land. In that sense, the name may originally have referred to someone living near a deer-marked boundary, lane, or tract of land, or to a place-name built on the same components. Because the surname is relatively uncommon and not strongly standardized in early records, its exact formation is uncertain.
History
Hartline is found chiefly in English-speaking countries today, especially the United States. The name appears to be a later stabilized surname rather than one with a single famous medieval line, and spellings have likely varied over time. In American records it is sometimes treated as a family-name form developed from an English place-name or from an older compound surname.
