Millwall Rovers were formed by the workers of J.T. Morton's canning and preserve factory in the Millwall area of the Isle of Dogs in London's East End in 1885. First founded in Aberdeen in 1849 to supply sailing ships with food, the company opened their first English cannery and food processing plant at Millwall docks in 1872 and attracted a workforce from across the country, including the east coast of Scotland, primarily Dundee.
The club secretary was seventeen-year-old Jasper Sexton, the son of the landlord of The Islander pub in Tooke Street where Millwall held their meetings. Millwall Rovers' first fixture was on 3 October 1885 against Fillebrook, a team that played in Leytonstone. The newly formed team were well beaten 5–0.
