Thanks to Stan and Geoff for their helpful information. Street numbering can still be confusing....looking recently at a directory for High Street East which began at Sans Street, the directory divided the street into north and south sides, and both sides seemed to have both odd and even numbers! And how about the half numbers? I've often seen the likes of number 4, and number 4 1/2; did this mean a small adjacent dwelling, or part of the main dwelling, or perhaps a dwelling to the rear of the main? Incidentally, still talking about Sans Street does anyone know more about the Sans Street Mission? Thanks Rob
