Thank you very much Annie and Spendlove for your precious advice. This is very useful. Indeed, it might be simpler to search for documents of interest on the National Archives website and then either order them in advance of a visit or indeed just ask them remotely for copies.
It is indeed curious that Martin Farnell's marriage and bankruptcy occurred at pretty much the same time. I think the questions I have, to which I may not find answers, are:
(1) Why did he marry Frances Matthews at the time of his bankruptcy, when he was about 58 years old and she was about 34, with an illegitimate daughter, Phoebe, born in 1796 (baptised in Lullington), who became my ancestor.
(2) According to his will, made in 1815, he left a certain amount of property, even though he was declared bankrupt in 1805. How did he come to still have all this property?
(3) How did he come to end up in Four Oaks in Sutton Coldfield, Warwickshire, and be buried (as far as I am aware) in Clifton Campville, Staffordshire?
Sorry, I am just trying to clarify my own questions here!
Thank you again for all of your help.
Yes, I have access to Ancestry but not Findmypast.
Best wishes,
Alan
