Sarah Burnham was born about 1759 in Essex, Massachusetts, the daughter of Westley Burnham and Deborah Story. She married Abner Poland, also of Essex, on 20 March 1783 in Essex. He was the son of Abner Poland and Dorothy Burnham. Abner served in the Revolutionary War and won a Badge of Merit for seven years and six months faithful service (signed by George Washington!). He received a bounty land grand in Enfield, New Hampshire as a reward for his service, so the family removed to New Hampshire.
