I am stuck at James CAMM born about 1861 in Aldgate, London.

I have an entry on the 1861 Census 5 Marsh Row, Poplar, Middx (RG 9/310 P99) and the 1881 Census 3 Strafford Street, Poplar, Middlesex (RG 11/510 p19)

From these I see that he married Jane ? from the Isle of Wight. They had several children: Jane, Thomas, Joseph, Henry, James and John.

I am trying to find the next generation back.
