Since 1859, attempts to resolve the question of the identity of a sailor from the 1845 Franklin expedition whose body was found that year on the south shore of King William Island have been complicated by contradictory evidence found with the skeleton. Documents found with the body implied the man was Harry Peglar, Captain of the Foretop, but the clothing indicated the man held a domestic rating, a steward or officer’s servant. This paper examines the question of the sailor’s identity through a review of the investigative framework of past attempts to ascertain the man’s identity. It then presents results of comparative DNA analyses conducted on the skeleton and on samples provided by descendants of Harry Peglar and six of the eight stewards. Comparison of DNA profiles obtained from the skeleton with those of descendants of the stewards yielded no matches, but comparison of the mtDNA profile obtained from the skeleton with a presumed descendant of Harry Peglar yielded a match with a genetic distance of 0. We conclude that the DNA and genealogical evidence confirm that the identity of the sailor whose skeleton was discovered in 1859 was that of Henry Peter (“Harry”) Peglar, Captain of the Foretop, HMS Terror.

A review of historical documents concerning the 1859 discovery of the skeleton of a member of the 1845 Franklin expedition on southern King William Island revealed a significant but previously unrecognized geographical error about the site’s reported and mapped location. Archeological investigations conducted in 2019 established the site’s correct location and the fact that it had unwittingly been rediscovered in 1973. Misconceptions concerning the site’s location and key aspects of its interpretation highlight the importance of careful evaluation of historical and archeological data regarding the 1845 Franklin expedition.
