Unfortunately, there are no baptismal records for that early date for that area. These are Roman Catholic records. Do you know what religion they were?
There is an archive in the National Archives (UK) called the 'Reproductive Looan Funds records, Templehouse loan association.' (1822-48). These records might be worth looking into. The catalogue number is: T/91.
You could also try checking the land records called the Tithe Applotment Books (1823-38) or the later Griffith's Valuation (1848-64). Griffith's is freely available here: www.askaboutireland.com
