Many thanks.
Can anybody see them in 1841? And if they can, is there a John Griffiths with them or nearby. Born about 1836. John Griffiths had no father (according to his marriage cert in 1860), and he is in Bedminster work house for the 1851 census, as far as I can work out.
So, I am looking at the possibility that the Lansdowns may have been bringing him up in 1841. Otherwise the most promising seanario comes from the fact that Carey Lansdown was the sexton of the church, and therefore was asked to be the witness due to his proximity.
