In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Sealand like this:
SEALAND, a township in Hawarden parish, Flint; 2 miles N W of H. village. Acres, 5, 514; of which 535 are water. Real property, £6,052. Pop. in 1851, 291; in 1861, 390. Houses, 66. The increase of pop. arose from reclamation of marsh land. A church was built here in 1866, and is in the early English style.
