McAnulty name

My great, great, great grandfather was Edward McAnulty married to Ann. He was born in 1768 in Northern Ireland. His son, John who came to Ontario, Canada with his wife Margaret, was born in 1804 and lived in Cantytrindle, Derryvullan, Fermanagh according to the 1821 Census. I will soon be in Northern Ireland and am hoping to find some information about my ancestors. Edward had three other sons that I know about---Patt 1808, Edward 1811 and Thomas 1819.
