Married by licence on 22 December 1817 at St Dunstan Stepney; John Tharp Thompson bachelor of this parish & Mary Aicken spinster of Lewisham, Kent.  The year is definitely 1817, yet there was an earlier baptism for their son.  Baptized 8 March 1815 at Shoreditch St Leonard, Charles John Thompson, son of John Tharp Thompson & Mary Aickin Thompson, gent of Trafalgar St City Road. Born 1 October 1814. 
I am reasonably sure of the ancestors of John Tharp Thompson, but have no further information on Mary Aicken. 
Baptized 8 April 1774 at St Andrew Holborn, John Tharp son of Thomas & Charlotte Thompson, Princes Street.
A John Tharp Thompson was on the Navy List for 1806 as a Lieutenant but was not listed in William O'Byrne's massive biographies of naval officers in 1846.  
I have not found any UK deaths, burials or probate records for this family.  Perhaps they went abroad.
Can anyone add to these details?
