‍    They moved to Jacksonville FL, where Frank owned a lumber business, and where they had 3 daughters. Frank was soon spending less and less time at home with his family, until Marie- suspicious of what was happening- hired a private investigator to look into the situation. The detective discovered that not only was Frank having an affair with his secretary, Mary Mallett, but he was also a dodgy businessman, of whom few had a good word to say (though some said that his wife and mother-in-law were hard to endure.)

‍    In 1912, Marie divorced Frank and, to escape the shame of a divorce, moved to the home of her great aunt, Isabelle Remshart Redding in Waycross GA. The youngest daughter, Frances Robinson Clarke, was renamed (whether officially is not known) Isabelle Redding Clarke, by which she was always later known. The family, including the now-grown children, returned to Savannah after the death of Aunt Issie in 1929.

‍    Only a few days after the divorce, Frank married his secretary, Mary Mallett, in Arkansas. They moved to Montclair NJ, where Frank again owned a lumber business. They had one son, Frank Jr, who attended Exeter and Princeton, married Katherine Hutchinson, and moved to Oxford MD. Frank Jr. and Katherine had no children. Later, Frank and Mary joined their son in Oxford, where Frank died in 1961. After the divorce, Frank had no contact with his first family, who knew nothing of his later life.
