I looked it up later and found out that it's generally conceded that they were all dead by the 1680s. But a story persists that a fellow named MacQueen killed the last wolf in Scotland - and, implicitly, in all Britain - after that, in 1743. (Henry Shoemaker mentions the story in the section of Extinct Pennsylvania Animals that concerns wolves.)
