Last Resort: Cancelled Land Records

[crb83]

Does anyone know how to go about searching through cancelled irish land records with info from Griffith's Valuation?
My family was from Clara (Kilbride Church of Ireland parish) and all church records are lost.  I have them in tithe applotments, griffiths, and they were there for only 2 years after civil registration started, they emigrated to NYC in 1866.

I'd like to try to use the land records as a census substitute to see if I can find if it was left in the hands of relatives upon death/emigration so maybe I can find some clues.

Would the land records be LDS microfilms or are they only available through Ireland's archives?
