Hi - Thanks for the quick response. I've had a quick look at my notes again, and John (who was 71 in 1901) was living at 14 Watson Street (which no longer exists, but I think was on the Headland), with George (age 22) and Beatrice (age 22) who I'm assuming are his Grandson and wife (due to the age difference). There is a toddler in the house also called George (possible John George W).
I remember my Dad telling me a story of how the 'Slimings' Clan came down from Scotland heading for London - the lazy swines we are, got to Hartlepool and gave up!!
I also found trace of a husband and wife in South Shields who were drapers - not the usual profession for a Slimings who were all in shipbuilding from an early age.
