Harmon Jones was the son of Harmon DeGraff Jones and Marion Bradfort Pierce. The mother lived with the family in the 1900 census. His mother’s family tree can be found in
“Pierce genealogy, being the record of the posterity of John Pers, an early inhabitant of Watertown, in New England”
Harmon’s parents lived in New Orleans in 1849 where his father bought a schooner named the Florinda, and left the port of New Orleans for the gold rush of San Francisco. He was never heard from again. In 1875 a British vessel got off course in the South Pacific and found the survivors of the Florinda on a small island, or so the story goes. That is documented in the same book.
His mother had a sister named Cornelia Pierce who was the wife of John Hoey also in New Orleans.
My interest is in the Florinda, because my great-great grandfather was the captain of the vessel. His name was James Kenmure and his letter to his wife is also in the book. If you are a member of Ancestery.com you can read the pages of the book. Good luck with your search.
