In January 1728 Ann Nepton set up a trust upon this Dunning’s Alley property for the benefit of seven successive beneficiaries, including her. On the death of Joseph Green junior, the son of Joseph Green senior, a cow keeper living near Shoreditch church, the property passed to the Company of Poulters’ for ever to pay £40 per annum to the poor people of Barking in the county of Essex "as shall be the most industrious and that do not receive Alms or reliefe of the said parish". A similar trust was set up for St. Boltolph’s Aldgate. Joseph Green died on 30th October 1764 and the industrious poor soon benefitted from the Nepton Charity.
The Dunning Alley land was eventually required by the North London Railway Company in 1862 and in 1865 for the City terminus of the Great Eastern Railway Company. By 1969 it was decided to invest the Nepton Funds in the Charities Official Investment Trust.
