Frank Fuller Sparke - Liverpool

[fraggle]

Hi

Does anyone know the where abouts of Frank Fuller Sparke on the night of 1901 Census?  I can't find him anywhere.  Born 1878, he was the son of Cornelius Sparke and Sophia Louisa Wiltshire and married Amy Thornton.  I'm lucky and do have a fair amount of info on him but I'm baffled as to where he was that night!  He was Mariner/Merchant Seaman so it is possible he was at Sea but I've no idea of the vessels he sailed on and so the search stops dead!
I know it's a long shot but I wondered if anyone has him at an address with one of their relatives that night as the Fuller is a bit unusual as a middle name!  His grandfather Joseph was a baptish minister and also had the Fuller Sparke.

Thanks for any little bit of info in advance!
