Hiram Brewster, one of the early pioneers of Walworth, was a native of New Hampshire, born near Dover on Dec. 21, 1806; learned the trade of a machinist, and in 1841, was married to Miss Achsha Mansur, a native of Vermont, born in 1812.

At his death, which occurred Jan. 18, 1861, he owned 300 acres of land, which he left to his wife, who has since carried on the same. She now owns 437 acres, 280 of which is worth $40 per acre and the balance valued at $20 per acre. The children are J. M. and George, both of whom are now helping take care of the estate (History of Walworth County, 1882).
