Dave, Livingston was a new county in 1830. For 1810 or 1820 census check Ontario, Genesee or Allegany counties. For 1790 Ontario and 1800 Ontario or Steuben. I sent this directly to David Shea a few days ago, forgetting that others on the list might be interested. The reference for this information is "Map Guide to the U.S. Federal Censuses, 1790-1920" by William Thorndale and William Dollarhide. (1987) Dick Rich
