Matthew, fifth son of the immigrant John Libbey, and his wife Agnes [Note: this is confused, confusing John the immigrant with his son John whose wife was Agnes. We know from other sources that Matthew was son of the immigrant and his wife Mary.], was born in Scarborough, Maine, in 1663, and died in March 1741. In 1690 he went to Portsmouth and thence to Kittery in the winter of 1699-1700. There he build a house of hewed timber, the upper story of which projected over the lower one so as to afford protection against the Indians in case they attempted to set fire to or break into the house, the projecting upper story having openings so that the inmates could shoot down those below without exposing themselves. In that house which stood for nearly one hundred years, he lived until his death. Some time before the second organization of the town of Scarborough, he, with Roger Deering, John Libbey and Roger Hunnewell, went down to Black Point and built a saw mill on Nonesuch river. His interest in that mill he afterwards gave to his three sons, William, John and Andrew. It is not probable that he operated the mill long himself. He married Elizabeth Brown, daughter of Andrew Brown, one of the principal inhabitants of Black Point. She survived him two or three years. Both were buried in the family burying ground where repose the remains five generations of their descendants, their graves marked by rough stones. They had fourteen children, the first six born in Scarborough and Portsmouth and the remainder in Kittery.
