John married Sarah Spall in 1746 in Wymondham.
They had a large family from 1747 (but need to be careful to be sure that children with parents named John and Sarah were all from this couple, as there were quite a few John Bunns, although I can find no other marriage to a Sarah).
He most probably died after 1768.
