A note relating to the birth date of Captain Francis Rawdon Moira Crozier R.N., F.R.S., F.R.A.S.

Abstract Prior to 2009, it had been generally accepted that Captain Crozier was born in September 1796 and most likely on the 17th of that month. Further research, published in this Journal, then suggested that upon a fresh scrutiny of the evidence the alternative date of 16 August 1796 was more probable. This note proposes that whilst the date of 16 August was of significance to Captain Crozier, that significance was other than natal and furthermore that alternative evidence, namely a letter dated 20 March 1810 from his father to the 3rd Marquess of Downshire, records his date of birth as being 17 October 1796.
