hi pentio, wonderful stuff my friend, but my first urban number seven appears in whiteabbey 1885! not 1898 under the new housing act, the next appears in greencastle 1893, still not under the new housing act, it all gets a little confusing to someone from outwith of belfast, no doubt it all makes sense, i was rather hoping that the urban number took in a few streets, which in turn could help determine the street where ancestors where born, looking at the map of belfast area, greencastle is a big place and so is whiteabbey, what year did the urban numbers disappear from birthlines?
