Britain took Cephallonia from France in 1809, during the Napoleonic Wars.  Together with Cerigo, Ithaca, Zante, Santa Maura, Paxo and Corfu, in 1815 it became part of the United States of Ionia.  The islands remained under British protection until 1863 when they were ceded to Greece.

Lord Napier, who ruled Cephallonia as governor and is remembered kindly in local history, named his daughter Emily Kefalonia.
