Thanks to Stan for his further thoughts and to Alan for information on the Sans Street Mission. The street numbering still seems to follow no particular rule, although I agree with Geoff regarding even and odd numbering which is certainly a feature of later streets. Looking at Sans Street, on the east side was The Ship Inn at number 1; a map I have from 1898 shows a public house which Corder lists as the Wheatsheaf at number 7, between the two pubs are four dwellings on this map; this wouldn't fit with consecutive numbering (not enough) but would fit with odd numbers as I'm told my ancestors shop at number 5 was double fronted, and if the shop next door at number 3 was similarly double fronted that would explain the number of dwellings. Does anyone have any photos of Sans Street in any books or otherwise they would be able to scan for me? Any would be much appreciated Thanks Rob [email protected]
