Glenn surname meaning
A surname from Irish or Scottish glen, “valley,” and from places or personal names built on that landscape word.
Confidence: Likely. The main story is well supported; some details of the deeper root are less certain.
The short story
Glenn is strongly associated with the Gaelic and northern English landscape word glen, “valley,” and may identify someone who lived by or came from such a feature. Glen and Glyn are related landscape or regional forms, while MacGlinn represents a separate Irish patronymic route that can share the spelling. Some families inherited Glenn from the given name rather than directly from a valley. Place is therefore the catalog lead, with likely rather than high confidence because personal-name and regional histories overlap.
