Cobb surname meaning
An English nickname surname from Cobbe or Cobba, likely referring to a large or well-built person.
Confidence: Likely. The main story is well supported; some details of the deeper root are less certain.
The short story
Cobb is chiefly traced to the medieval byname Cobbe or Cobba, with a related Old Norse form Kobbi. The byname is commonly connected with “lump” and may have described a large, solidly built, or otherwise conspicuous person. Some Cobb lines may instead preserve a shortened form of Jacob, so the surname need not have one origin in every record. Cobbe and Cobba are useful historical forms rather than proof of a single household. Nickname is the catalog lead, with likely confidence because the byname explanation is strong but competing personal-name routes remain possible.
