↑ The official web site of the British Monarchy puts his birth at "around 1028", which may reasonably be taken as definitive. The frequently encountered date of 14 October 1024 is likely spurious. It was promulgated by Thomas Roscoe in his 1846 biography The life of William the Conqueror. The year 1024 is apparently calculated from the fictive deathbed confession of William recounted by Ordericus Vitalis (who was about twelve when the Conqueror died) ; in it William allegedly claimed to be about sixty-three or four years of age at his death in 1087. The birth day and month are suspiciously the same as those of the Battle of Hastings. This date claim, repeated by other Victorian historians (e.g. Jacob Abbott) , has been entered unsourced into the LDS genealogical database, and has found its way thence into countless personal genealogies. Cf. The Conqueror and His Companions by J.R. Planché, Somerset Herald. London: Tinsley Brothers, 1874.
