Hi
The Benjamin Wimbush who died in Banbury registration district in 1867 aged 78 states on the 1861 census he was born in Bourton Oxfordshire (69 on that census, 59 in 1851 confirming his birthplace). He lives in Warmington Warwickshire which is covered by Banbury registration district. On the 1851 census there are two Benjamin Wimbushes. The other was aged 73 and born in Tingewick Buckinghamshire (living there) and also there in 1841. There seems no obvious death registration for that Benjamin. Neither man's baptism is on the IGI.
The Thomas Wimbush who married Hannah Coleman 5th August 1772 in Culworth, Northamptonshire had according to this tree at least one son called Thomas who died in Little Bourton Oxfordshire
http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=REG&db=sknowles&id=I43389How has it been proved that the Northamptonshire/Oxfordshire Wimbush family connects to the London Wimbush family? If it has been proven and Elizabeth was still alive at the time of the marriage to Hannah then the marriage would undoubtedly be bigamous since only the extremely rich could afford the Act of Parliament that would be necessary at the time to obtain a divorce.
The Elizabeth Wimbush who died in 1821 seems to have left a will
London Consistory Court - held at the LMA
probated February 1821
Elizabeth Wimbush widow
New Brentford Middlesex
Formerly of Bankside Southwark Surrey

http://www.cityoflondon.gov.uk/wills/Wimbush Thomas (Junior) 1765 Aug 21 Bachelor , Saint Saviour, co. Surry , married Elizabeth Smith
Does this marriage in Southwark mean the two Wimbush Prerogative Court of Canterbury wills in St Mary Newington Southwark are related?
Will of Thomas Wimbush, Gentleman of Saint Mary Newington , Surrey 27 February 1776 PROB 11/1017
Will of Susanna Wimbush, Widow of Saint Mary Newington , Surrey 23 August 1788 PROB 11/1169
If so since Susanna's will was proved in 1788 it may hold useful information.
