Isaiah was left an orphan in early boyhood, and soon entered on a somewhat adventurous career as a "sailor-boy," first in the cabin and finally as a fully-equipped seaman. With other sailors he paid his twenty-five cents to inspect Robert Fulton's original little steamer and joined in predicting the results - wise and otherwise. His "protection paper," No. 3,123, U.S.A., to insure against seizure by the British on the high seas, had at one time been the possession of his grandson.

Upon attaining his majority, he left New York Cty and invested his savings in unimproved land near Unadilla Forks, where he soon married Keturah, daughter of his neighbor. Keturah is a seventh generation descendant of Walter Palmer, who came to this county in 1629 and eventually settled in Stonington, New London Co., CT.

Per census lived Plainfield, 1820 thru 1850.

He served in the Navy during the War of 1812. They resided in Groton; Hebron, Toland Co., CT; Marlboro, Ulster Co., NY; Berne, Albany Co., NY; and Springfield, Walworth Co., WI.
