The historic London Tecumsehs were a professional men's baseball team in London, Ontario, Canada, that were first formed in 1868 — a merger of the Forest City Base Ball Club and the London Base Ball Club — which, according to George Railton's 1856 London directory, consisted of officers J.K. Brown, Dr. J. Wilkinson and J.D. Dalton and 22 players who practiced twice a week on the military grounds. Wikipedia
