For a more complete historical listing, including extinct, dormant, abeyant, forfeit dukedoms in addition to these extant ones, see List of dukedoms in the peerages of Britain and Ireland . </P> <P> In the peerage of England, the title of Duke was created 74 times (using 40 different titles: the rest were recreations). Twice a woman was created a Duchess in her own right (but only for life). Out of the 74 times, 37 titles are now extinct (including the two women's), 16 titles were forfeit or surrendered, 10 were merged with the crown, and 11 are extant (see list below). The first, Cornwall, is a title that automatically goes to the heir apparent (if and only if he is also the eldest living son of the Sovereign). One of the duchies that was merged into the crown, Lancaster, still provides income to the sovereign . All but three of the non-royal ducal titles which became extinct did so before the 19th century (the Duke of Leeds became extinct in 1964, the Duke of Newcastle in 1988, and the Duke of Portland in 1990). The last English dukedom to be forfeit became so in 1715 . The last British dukedom to become extinct was the title of Duke of Portland in 1990 . </P>
