Hector has occasionally been used as a given name since the Middle Ages, probably because of the noble character of the classical hero. It has been historically common in Scotland, where it was used as an Anglicized form of Eachann.
This was a common name in classical Greece, and, due to both the saints who carried it and the favourable meaning, it came into general use in the Christian world, being especially popular among Eastern Christians. It was however rare in Britain before the 19th century. Famous bearers include three tsars of Russia (in the Russian form Fyodor) and American president Theodore Roosevelt (1858-1919).
