This is biographical book. John Motley, the great-grandfather of the subject of this Memoir, came in the earlier part of the last century from Belfast in Ireland to Falmouth, now Portland, in the District, now the State of Maine. He was twice married, and had ten children, four of the first marriage and six of the last. Thomas, the youngest son by his first wife, married Emma, a daughter of John Wait, the first Sheriff of Cumberland County under the government of the United States. Two of their seven sons, Thomas and Edward, removed from Portland to Boston in 1802 and established themselves as partners in commercial business, continuing united and prosperous for nearly half a century before the firm was dissolved. The earlier records of New England have preserved the memory of an incident which deserves mention as showing how the historian’s life was saved by a quickwitted handmaid, more than a hundred years before he was born. On the 29th of August, 1708, the French and Indians from Canada made an attack upon the town of Haverhill, in Massachusetts. Thirty or forty persons were slaughtered, and many others were carried captive into Canada.
