Hi Gill and Rutti!
That is indeed them from 1871 (sorry, I already had it).
Alfred seems to have died between Oct 1878 and Mar 1881 as I have him at his daughter Caroline's wedding. However, this may not be the case. I am relying on the fact that a registrar will normally write deceased by father's name.
Emma Jane may indeed have remarried, or died?, by 1891, as indeed she was a widow in the 1881 census. Ten years is a long time.
That could indeed be Albert's death in 1885. Another possibility is a mistranscribe of his age in 1881!
