Sir Frederick regained the seat of Winchelsea in 1806 but retired in 1807 when the seat was taken by Sir Oswald Mosley . In the General Election of 1818 , Sir Frederick failed in his attempt to win the pocket seat of Cockermouth as part of the ' anti-Lowther movement ' spearheaded by Henry Brougham . In one of his last political acts , Sir Frederick signed the requisition of a county meeting in Cumberland in October 1819 to consider the Peterloo Massacre having written to Henry Brougham on the 30th of September : I made this addition opposite my name , ‘ and also to consider of the necessity of a reform in Parliament ’ . If that question is not brought forward , it might appear that a change of ministers was our only object , but I suppose most of us will be of opinion that no change can be of much use without a reform in the borough system . It is not known when Sir Frederick began an affair with Hannah Bowerbank , a ‘ companion ’ to Sir Frederick ’s mother at Hutton in the Forest , according to the memoir of Sir Frederick ’s grandson , later Sir Francis Patrick Fletcher Vane , 5th Baronet . On 22 August 1794 , Hannah Bowerbank gave birth to a daughter , also named Hannah . A son was born on 9 July 1795 , Walter Vane , and the ‘ intimacy between Sir Frederick and Hannah continued and they lived together at various places in Cumberland and among others at Broughton Hall in the parish of Bridekirk ’ . The children were baptised on 16 July 1795 at St Mary ’s Parish Church , Marylebone , London
