Hi Imison,
I do love a good mystery and have to confess I'm feeling a bit pleased with myself for making a little bit of progress on this one.
Here's what I've found:
1891
86 Smyrks (?) Rd, Newington St Mary, London
Lane, William H, abt 1870 Brixton, London, Head, Civil Service, telegraphist
Lane, Emma L abt 1866 Woolwich, Kent, Wife
Lane, Alice E abt 1888 Southwark, London, Daughter
Lane, Henry A C abt 1890 Camberwell, London, Son
MARRIAGE REF
September q. 1887, Lambeth, Greater London 1d/648

Russell Grove, Lambeth, London
Henry Lane abt 1844 Keddlesworth, Norfolk, Head, Carpenter
Grace Lane abt 1844 Truro, Cornwall, Wife

These people appear to live in the same house - and there may be a connection (ie Truro)

Great frustration, however, that I cannot find any members of the family in 1901, nor Emma Morris/Lane in any other census. With luck, though, her marriage cert should give you the name of her father at least.
Do let me know how you get on - I've become quite involved in them all!
Cheers,
Ros
