 Edmund Dunch was created Baron Burnell of East Wittenham in April 1658, but this barony was not regranted.The male line failed in 1719 with the death of his grandson, also Edmund Dunch, so no one can lay claim to the title.The one hereditary viscountcy Cromwell created for certain, (making Charles Howard Viscount Howard of Morpeth and Baron Gilsland) continues to this day.
