The first record of land purchased in the area that became Armada Township was made by John Proctor in 1825. Twenty-three more families had bought land in the rural area by 1832. Until 1832 the area was part of Ray Township. At that time a meeting was called to organize a separate township. The vote won by two and Armada Township was founded. When the discussion began to choose the name for the new township, legend says that "Hosea Northrup jumped up and shouted the name 'Armada'". The name was accepted.
