I am having trouble finding the Cowley family in the 1951 census. I have searched for all children individually for the census including spelling errors.
Head is Matthew George Cowley born 1810 London/Clerkenwell Engraver
Wife Mary Ann Cowley nee Hay born 1816
George W Cowley born 1839
William S Cowley born 1843
Mary Ann Sophia Cowley born 1847
Henry M Cowley born 1848
His wife died in 1854 and they were living at 18 St Johns street Clerkenwell.
But I cannot find it in the census
