The Boston Public Library has digitized tax lists for 1780, 1782, and 1783.
Although these tax lists are from the Revolutionary War period, they can’t automatically be used as “proof” of service for the Sons or Daughters of the American Revolution. Why? Because we don’t know when and how the tax money was employed. To be considered “service,” the tax money needs to have gone towards the support of the cause.
Town meeting records may provide evidence as to how the money was used.
