. There was great confusion over the succession after the death of the eleventh Baronet in 1883. The rightful heir was believed to be Edward Berkeley Philipps (later Mansel), son of Courtenay Philipps, son of Richard Mansel, younger brother of the tenth Baronet. However, it was widely believed that Courtenay Philipps's first marriage was invalid. The title was therefore assumed by Edward Berkeley Philipps's half-brother Richard Philipps (later Mansel) as the twelfth Baronet. On his death in 1892 the title was assumed by his son Courtenay Cecil Mansel, the thirteenth Baronet. However, in 1903 the latter discovered evidence that his grandfather's first marriage was indeed valid and relinquished the use of the title in favour of his uncle Edward Berkeley Philipps (later Mansel), who became the twelfth Baronet. When he died childless in 1908 the title was resumed by his nephew Courtenay Cecil Mansel, the thirteenth Baronet. Sir Courtenay Cecil Mansel later represented Penryn and Falmouth
