Always search a few doors up and down to see who is around - on other censuses this can often be other family members, including children staying with relations on the same page, or even future husbands/wives.
If you see the other lodgers - they are from England, Ireland and Wales, so the tailor has travelled about the least distance of any of them.
Sorry, got to go, will try and remember to look for them later - could you just post what else you know about them so anyone can help you look for them?
