Robert lived on the Square from about 1822 to around 1834, and according to the trade directories, lived variously at number 2, number 4, number 9, number 10, number eleven and numbers seventeen and eighteen. He must have been knackered, from lugging all his gear around!
You may just suspect that as more houses were built and occupied, the house numbers went up, but in actual fact he lived first at number 7 ( modern number) up to around 1825, and then did actually move house to reside at number eleven ( modern number) for the reminder of his time in the locality. Part of the confusion was that the census takers, in three of the years, decided to number houses anti-clockwise rather than clockwise ( reasons unknown), but only through painstakingly mapping out everyone who lived there every year, and the addresses they gave, can you put together an accurate record of which of the current actual houses were occupied when.
For ease of identification, I use the 'final' address number where possible, though it gets tricky with the corner houses, and the fact that the door numbers which still adorn some of the entrances are... err.. actually wrong. This is due to various later knockthroughs and removal of doorways.
It would take more space than I have here to explain it all thoroughly, so I'll probably be devoting a chapter to it in the book.Post 1837 it is relatively straightforward to follow, but prior to that, I warn you in advance, it may possibly melt your brain trying to follow. Which is why I have a lovely colour-coded map to show actual residence in actual location, along with the number it was called in each year.
It was a very painstaking process, but doing the puzzling out and researching first has made later research so much easier. So the lesson I guess is that it pays to lay the groundwork first, however long it takes. Oh, and that colour-coding is wonderful!
