Sir Anthony Wescombe was the son of Sir Martin Wescombe, who was the British consul in Cadiz. Anthony was deputy-commissary-general and deputy- judge-advocate, commissary of the musters in Minorca, and finally deputy muster master general of the forces, until his death 1752. 
As a young man he served as a captain in William III’s forces. The diarist Thomas Bellingham records his arrival in Preston on 16 February 1689, and was frequently in his company for the next few weeks. The pair were reunited when both were serving in Ireland later in the year, as noted in Bellingham’s diary entry for 6 November 1689.
