Frederick Hagenow (January 1845 - April 25, 1913) was the husband of Julia (Goodwin) Spencer, a descendant of Ozias Goodwin, and one of the oldest German setlers in Manchester, Connecticut. He was born in January 1845 to William Hagenow (Jan. 14, 1803 - Nov. 9, 1871) and Fredericka Hagenow (May 1, 1806 - Nov. 9, 1881). Shortly after coming to Manchester from Germany, he was employed by Cheney Brothers Silk in the drying department and was foreman of that department until he was struck with illness at the end of 1912. He was a member of Manchester Lodge, A.F. & A.M., and took an active interest in the order in his early life. For many years, he was a resident of Pine Street in Manchester, living in a house which was removed to make room for a ribbon mill. He died on April 25, 1913.
