The 1851 census lists him as being born in Hagbourne c. 1811. He was married in Clifton Hampden and was subsequently buried there with is wife. I have a photo of the grave.
So, he could have been wrong about his birth year or even place. The villages I am concerned about are all close (Drayton, Clifton, Radley and Hagbourne) so he may well have been confused.
I will look for him in Clifton and also Drayton and Radley. I am so keen to locate his parents and siblings.
