Thanks Tazzie.
It seems strange that Jane got married in Kent in 1854 when she was still in Bedfordshire in 1851. I see that the two witnesses to the wedding were Harris so perhaps she had moved to live with relatives.
It seems that James' second wife Kate was from Aspley Guise with the family living in St Pancras in 1891 with their 4 children. William the eldest being born in Woburn in 1880. However, I cannot find the family in the 1881 census nor see any sign of Jane's son Frederick after the 1871 census
