The Late Samuel L. Gouverneur
Samuel L. Gouverneur died on Friday, September 29th, at his residence, Needwood, near Harper’s Ferry. Mr. Gouverneur was the son of Nicholas Gouverneur, an old and respected resident of this city and well known to many of our older citizens. Early in life, when a promising member of the bar, he married the daughter of President Monroe and served as his private secretary during his two Presidential terms. He was subsequently appointed postmaster of the city of New York and held that position under President Jackson. Many years since he retired from public and professional life and has lately resided with his wife by a second marriage, a Miss Lee, of Maryland, near Harper’s Ferry, in that state. Mr. Gouverneur was genial and accomplished and possessed a remarkable faculty of gaining friends wherever he might be. His death will be regretted by many who remember his lively and interesting conversation and his courtly manners.
