Son Of A Gun 〈Edge〉

The most lexicographically sound origin comes from the British Royal Navy. Ships’ logs from 1740–1790 indicate that “gun” was slang for a naval cannon. During long voyages, women (often sex workers or sailors’ wives) were permitted on board. If a child was born between the guns on the gundeck—often with the father unknown—the boy’s enlistment papers would list “son of a gun” as a placeholder for his surname. This denoted illegitimacy, low status, and a lack of legal protection. Admiralty court records from 1762 show one such boy listed as John, son of a gun, gunner’s mate, no surety .

A competing, though historically unsupported, origin involves the naval tradition of firing a cannon during childbirth to speed labor or ward off evil spirits. While romantic, no primary medical or naval log corroborates this. The present author suggests this folk etymology emerged in the 19th century as a sentimental revision—transforming the “son of a gun” from a bastard of violence into a child of ritual. This revision allowed the phrase to shed its most shameful connotations. Son Of A Gun
