Initially known as Great Choptank Island, the island became identified with a series of local families. It was owned by Matthew Tilghman's family from 1752 and has been known as Tilghman Island ever since. During the War of 1812 the island was briefly occupied by the British, who obtained provisions for their military forces. The community of Tilghman appeared in the 1840s. The economy shifted from farming to greater reliance on oystering and fishing as markets developed in Baltimore and Washington, aided by steamboat service in the 1890s.
