Tinner was the daughter of Mingo Proctor and Tenor (also known as "Old Tenor" to differentiate her from her daughter). Tenor was enslaved by the Reverend Roger Newton of Greenfield, Massachusetts. By 1790, the family was living in Colrain, Massachusetts, where Mingo is listed as the head of household for that year with three people noted in the "All other free Persons" column. Tinner was probably one of those three people. Both Greenfield and Colrain, vital records note the 1814 marriage of Tinner Proctor to Peter Green, Jr. of Colrain. He was 27 years old.
Newton kept a combination record and diary where he noted births, baptisms, weddings and deaths, and he occasionally wrote in the diary section about various people he knew. In August of 1790, he wrote: "Thursday 2d call to see Tinner [in Colrain, Massachusetts] who was probably more glad to see me than any Person I had met with in the journey may Heaven take Care of that poor african Superior in her Moral Disposition, to many of other Notions-".
In that same document: "Sept. 20. 1767. Isaac, my Son & Tinner, my Negro Girl" Baptism record.
