Ambrose Swallow, the ancestor of the Swallow families of New Hampshire and Massachusetts, was an early resident of Chelmsford. He married December 2, 1668, Mary Martin. In the return of the marriage to the county his name is written Ambrose fearlon. This very probably is an error in transcribing. His name is uniformly written Ambrose Swallow in the records of Chelmsford and in probate record. He died in Chelmsford, October 25, 1684. His wife, Mary, married, second, Samuel Warner of Dunstable. The inventory of his estate, dated November 3, 1684, amounts to £230-17-6, and includes "His homelott within fence with orchard & housing on same; His old field and land adjoining; His meadow Billerica bounds; His Spring meadow & upland adjacent; 5 cows, 2 oxen, 1 heifer, 2 calves, 1 horse, 18 swine, 2 bibles & other books, arms, ammunition, 5 Bbls Cyder, flax, hemp, yarn, & Tobacco &c."
