Annuity money came from the Six Nations Trust Fund.  This fund was set aside for the Six Nations by the British Imperial government made up of money from the lease or sale of Six Nations land.  This money was not only supposed to grow in value due to interest, but the Six Nations were to have access to it if ever they needed it.  In reality, the funds were much less easily accessible; they were to be held in trust by the British, and later the Canadian government.  Yearly, a small portion of this money would be given to each member of the Six Nations.
