Armstrong surname meaning
English and Scottish nickname meaning “strong in the arm,” with Gaelic translation and regional alternatives.
Confidence: Likely. The main story is well supported; some details of the deeper root are less certain.
The short story
Armstrong is the kind of surname that reads like a medieval byname: arm plus strong, probably praising or identifying someone known for physical strength. Scottish Border families made the name prominent, while in Ulster it could also represent Gaelic surnames translated or adapted into English, including forms associated with a strong man. The literal phrase is therefore a useful English lead, not proof of a single feat or ancestor. Nickname is the closest type; likely acknowledges the Gaelic and regional routes that share the modern spelling.
