Perriton L (2012) Depositor trends in the Limehouse Savings Bank, London, 1830-1876. http://www.savings-banks.com/SiteCollectionDocuments/perriton.pdf
First paragraph: The Limehouse Savings Bank (previously the Limehouse Provident Institution for Savings) was founded in 1816, one of the many savings banks that were formed in the early decades of the 19th Century in Britain. According to Horne there were 27 savings banks in the London metropolitan area by the end of 1819. Many of these pre-1819 banks identified by Horne map directly on to London’s densely populated inner-city areas such as St Martins Place, Covent Garden, Moorfields and Southwark. In the six square miles encompassing the newly established London docks and its industrial hinterland directly to the east of the city and known generically as the East End there were three savings banks – Whitechapel, Limehouse and Poplar. In 1976 a set of nine account ledgers of the Limehouse Savings Bank covering the period 1816-1876 were found in the crypt of a local church, close to the site of the bank’s 19th century premises.
