The subjoined interesting sketch of an ancient dwelling-house and of a family which has inhabited it for several generations, was furnished by a distinguished friend, Thomas Coffin Amory, Esq., of Boston, who traces his ancestry on the maternal side to the family in question. Nor, in producing this highly interesting sketch, could I overlook Joshua Coffin, the historian of Newbury and a resident of that town, from the originally extensive territory of which various adjacent towns were eventually formed. He was possessed of many amiable qualities and inspired by the true antiquarian spirit, and laboriously pored among the not very carefully kept early records of the original settlement, and brought much out of chaos well calculated to illustrate its former history. Mr. Amory has, on various occasions, shown the spirit of a careful historical student and of an intelligent and zealous antiquary. His recent contributions to that excellent periodical, "The New England Historical and Genealogical Register," which has become of inestimable value, as a collection of facts illustrative of early New England history and biography, have given great pleasure to multitudes of readers,--especially his vivid and graphic descriptions of certain ancient and storied mansions in Boston and Cambridge, and of their former inhabitants. Let us hope that researches of such abundant interest and value will soon claim and gain a still larger share of the public attention in a collected form. MY DEAR SIR,--In your reminiscences of Newburyport you must not forget Joshua Coffin its historian,--one of the best of men, whom no one knew but to love. I see him now as he came to visit me several years ago, when he was representing his native town in the General Court, a fresh, hale, cheery gentleman, full of pleasant anecdotes relating to the past. He owned and occupied the Coffin mansion, which had been the abode of seven generations of his family and name. Out of its portals had issued numberless admirable men and women, and from among the former, a large share of college graduates, at Harvard and other New England colleges, of lawyers, clergy, and soldiers, to do good service in their day and generation.
