Glenn
A surname most likely from a place-name or from the word for a narrow valley, with strong Irish and Scottish associations.
The #669 most common surname in the United States (2010 Census) — about 1 in every 6,049 Americans shares it.
Etymology
Glenn is usually linked to the Celtic word for a glen, meaning a narrow valley. In Irish and Scottish naming, it often reflects a place called Glen or a surname formed from that landscape term. Some historical references also connect it with Irish names spelled Glynn or Glinn, suggesting overlapping or anglicized forms rather than a single simple origin.
History
The surname is well established in Ireland and Scotland and also appears in English-speaking communities more broadly. Nineteenth- and early-twentieth-century surname writers often grouped Glenn with Glynn, Glinn, and related spellings, which shows how fluid the spelling was in records. In the United States it became a fairly common surname through immigration from Ireland, Scotland, and Britain.

Fun fact
Because glen names are so common in Gaelic-speaking areas, Glenn can be one of several surnames that look English but have a distinctly Celtic landscape origin.
