According to research I found while working on The Fowlerville Chronicles, the first two teachers in the area were Michael Handy, son of Calvin Handy, and Angeline Adams, daughter of Amos Adams, the man credited with platting the area. This was in 1838.
While working on additional research, I recently came across the following short article, published in The Fowlerville Review, mentioning the death of Angeline Adams in 1895:
E.A. Metcalf received a telegram from San Francisco, Cal., on Tuesday, announcing the death of his aunt, Miss Angeline Adams, at her home in that city. She was a resident of this county for over thirty years, leaving for California in 1867.
