As usual Geoff I think you've come up trumps. Thank you. The burial I found on Familysearch pilot site and FreeREG was on 29 March 1850 at Sleaford. FreeREG gives the burial place as St Denys, Sleaford, so I would have expected his death to be registered in the March quarter 1850, but because I couldn't find the death on FreeBMD, or FindMyPast or Ancestry, I thought perhaps it had been registered the following quarter under the name of Joseph. I'll order the John Branch certificate from GRO when I get back from holiday. (I can give the name Brand or Branch which usually works when I have the correct ref.no).
The info I quoted was from an e-mail I received from Customer Service Centre,
Lincolnshire County Council in response to one I sent to them asking if they would be able to look for a death registration if I didn't have full details.
Roger - No, no connection to the other cabinet makers (my brain is going which Stanton was the cabinet maker?). John Brand was the great grandfather of my maternal grandfather, the Stantons are my paternal ancestors.
