The Hubon family migrated from France to America sometime before the late 1700s. Stephen Hubon moved to the Caribbean island of St. Thomas, perhaps to work with the tobacco or sugar plantations. His son Henry was born there ca. 1788. When he was approximately fourteen years old, Henry was sent to the United States for his education. However, due to a slave revolt shortly before the boat sailed, the boy's parents were never heard from again, his education money stolen, and Henry entered an apprenticeship in Salem, Massachusetts, where he eventually became an undertaker. Henry married Frances Dywer in 1818. Their children included Frederick (born Stephen Frederick), Henry G., Edward, Mary, and possibly others. At age 22, Frederick traveled to California as a "forty-niner," and was joined shortly thereafter by his brother, Henry G. They lived in Stockton and the new town of Benicia until Henry G. became sick and returned to Salem, with Frederick following a few years later. Frederick married Sarah Livingston Allen in Salem in 1858 and had four children: Frederick Lincoln, Clarence Edward, Fannie Dwyer, and Irving Allen. In 1868, Frederick and Sarah sailed to San Francisco and then moved south to San Diego, where their fifth and final child, Leonard James, was born.
