3 February 1714 (OS) John William Leaser of Saint Pauls Covent Garden Working Goldsmith paid apprentice indenture duty for Matthew son of John Pratt of Saint Martins in the Fields Hatter deceased.
11 October 1718 John William Leaser of Saint Pauls Covent Garden Working Goldsmith paid apprentice indenture duty for Marke son of Caln Wilts Taylor.
