The child you have as
8. Henry James Baldwin
appears to me in fact to be Henry Simons Baldwin, birth reg Mar qtr 1873 Tonbridge.
Simons was his mother's maiden name (Henry Kennard Baldwin m Mary Nicks Simons, Mar qtr 1861 Williton).
I have seen that in 1881 he is enumerated as Henry James Baldwin but I think that is an error by the enumerator. I have also seen that there are other people with similar names in Kent who may confuse matters.
In 1891 he is still with parents as Henry S Baldwin. He marries Laura Marina Blowey in West Ashford in Sep qtr 1898; they're childless in 1901 when he gives his birthplace as Southborough. He probably dies in Ashford, Sep qtr 1950.
