Hi Joejoerey1,
dont know if this will help,
City of London Brewery Co Ltd, Hour Glass Brewery, Upper Thames Street. Founded by 1431 and was acquired by the Calvert family in 1759. Registered in 1860 as above and was reconstructed as the New City of London Brewery Co. Ltd in 1891 and was reverted to the original title in 1895. Due to increased trade, brewing was transferred to the Swan Brewery Fulham in 1922 and the Hour Glass Brewery was used as a warehouse. Brewing continued at Fulham until 1926 when many public houses were sold to Hoare & Co. Ltd. In 1919 Nalder & Collyer's Brewery Co Ltd of Croydon was acquired. The majority of the Nalder & Collyer tied houses were sold to Ind Coope Ltd in 1936. The Hour Glass Brewery was destroyed in an air raid. The final connection with the brewing trade ended in 1968 with the sale of 20 public houses to Allied Breweries, but the company is still in existence as an investment trust.
Only one takeover, apart from the Wenlock Brewery Co Ltd, has been made by a brewery outside London. This was when Tollemache Breweries Ltd of Ipswich acquired Collier Brothers, Essex Brewery, St Jamess Street, Walthamstow in 1920. Founded by Williams Hawes in 1859. Brewing ceased in 1972 and the brewery has been demolished.
I did a quick search on google and found the above, if you enter Walthamsow breweries you will find a lot of info on breweries around the Walthamstow area, hope this helps you a bit.
