Hi Carole People moved a lot as their needs changed, more children or less children, or their means changed so a cheaper place to rent was needed Or as you say the house numbers may have changed, either a new road, or houses between others, and at times for post & local organisation etc Remember the census is a snap shot of one day or night every ten years Check the neighbours to see if they are the same in subsequent census, or birth marriage or death events between the census You are using the house number, and not the schedule number I presume?
