In 1854, prior to his passing, Isaac Bronson made George A. Fairbanks a trustee of Sunny Point for Sophronia Bronson. Fairbanks paid $3,000, and the step was taken either to protect Sophronia after the death of her husband, or for financial reasons. After her husband's death, Sophronia Bronson remained at Sunny Point. Deed records dated November 1856 indicate that Mrs. Bronson was in Palatka at that time. Donations made to St. Mark's Church up to April 1860 suggest that she was at Sunny Point until the outbreak of the Civil War. At that time, she probably returned to her home state of New York, although the earliest record of her being there is in June 1866. Sophronia Bronson died in Morristown, New Jersey, in June 1874.
