It looks like Knockalane could be in the Roman Catholic diocese of Muckalee. If so, then there are church records available from 1801 (baptismal records) and 1809 (marriage records). These are available in the National Library of Ireland, Pos. 5026, or the Church of Latter Day Saints, ref. no. 0926200 item 1-5. If you have any difficulty, you could also try writing to the parish priest in the areaw.
You could 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 and here: www.failteromhat.com Failte Romhat also has lots of other useful documents you could try checking.
Please make sure you link anyone else in your family who is interested in their Irish heritage to our site - and indeed anyone else you know of Irish heritage.
