Alexander Leak was hired by Hester Lynch Piozzi ca. 1806 to serve as steward at her Brynbella estate near Denbigh, Wales. In 1813, he was commissioned to oversee repairs and troublesome tenants at Piozzi's Streatham Park estate near London. Piozzi resided in Wales and Bath, and leased out her life interest in Streatham Park. On 1813 Oct. 9, Leak married Ann Glover, who had been employed as a Piozzi servant since 1809. They had one child, Alexander Piozzi Leak. Leak assisted in the auction of contents of Streatham Park in May of 1816, and died the following month.
