I am not sure what you are looking for here. Do you think this is a different Louisa than the St Pancras one and therefore a different possibility for your Thomas?
Alfred and Louisa, with Mary and Charlotte are at 1901 743 /5 /1
They are also in 1911.

You mention a tree in your earlier post where there is a child added:
Charles Sydney Herbert Harris b 1889 Woolwich. His mothers name was
Spiller which is where I got my information re Harris/Spiller.
