Maybe someone can answer this query. I have ancestors in the 1851 Census Westoe Durham St Stephens district, Heugh Street, David and Mary Ann Irving 5 children, monther-in-law, and g.daughter.  Now I cannot find them in the 1861 census, tried searching their neighbours in the 1861 census and cannot trace them either. Is there a missing district here or page, I have found the children on later census, but not in Westoe, one in South Shields, gloucestershire, one in New Zealand, the other two I think I have as well. Where is David and Mary Ann, Catherine Oldham died, have a death certificate, not sure if this is right, and g.daughter nowhere to be found, even a birth.  Any suggestions Valerie Wilson
