Quote from the National Archives of Ireland web site:
No manuscript returns survive for 1861, 1871, 1881 and 1891. There are some returns for 1821, 1831, 1841 and 1851 covering parts of counties Antrim, Cavan, Cork, Fermanagh, Galway, King's Co. (Offaly), Londonderry (Derry), Meath and Waterford, and there is a list of names of heads of household in the returns of 1851 for Belfast City and Dublin City (see the list of 19th century census returns in the Reading Room or consult The 1851 Dublin City Census, Chart's Index of Heads of Household CD-ROM compiled and edited by Seán Magee, Eneclann, 2001).
There are also census search forms for each county giving the results of searches made in the returns of 1841 and 1851 for pension purposes (see the separate list for each county available in the Reading Room), and some other copies made from the returns of 1821-1851 (see the list of 19th century census returns - miscellaneous copies and certified copies available in the Reading Room).

You may be lucky, it must be worth a try.
