[1]: 4 When in 1839 Kingsley sold his Fort George Plantation and moved his complex mixed-"race" family to Haiti, Gibbs purchased it.
[5] In 1851, giving his address as Mayport Mills, Duval County, he advertised the products of the United States Mutual Insurance Company.
[1]: 11 When Kingsley died in 1843, Gibbs, an executor of his will,[7] inherited 1,000 acres (400 ha) in St. Johns County, the books from his library, his weapons, the schooner "North Carolina", and one twelfth of the estate, including slaves.
[1]: 5 Shortly before his death he wrote memoirs covering in some detail life at the plantation, which indirectly illuminate Kingsley's era.
By good fortune this then-unidentified manuscript reached the park manager at the Kingsley Plantation State Historic Site, and it has been published and annotated.
