It is not known whether Langharne can be identified with the man who died 27 Dec. 1631, and whose inquisition post mortem was taken at Horncastle, Lincolnshire on 1 May 1632, when he was described as ‘late of Cheshunt, Hertfordshire, gent.’
Whatever his background, by April 1585 he was Sir Walter Ralegh’s secretary, reported to be concerned in a plot to rescue Mary Queen of Scots from Tutbury, when he was described to her, probably falsely, as a good Catholic, willing to do her service, and particularly useful because of his master’s friendship with her gaoler (Sir) Amias Paulet.
