Information please

My great-grandmother was a direct decentdent of William Keays; born 24 Dec 1787, Ballyknocken, Fenagh, Carlow, Ireland. He married a Ellen Fry, Born:14 Nov 1798, Castlewellan, Down, Northern Ireland on 21 Mar 1819, Diocese of Ossory, Ireland. William and Ellen Keays subsequently emigrated to Lanark County, Perth, Ontario, Canada.(date unknown)whereupon they had 10 children; one of them Thomas was my great-great grandfather. I plan on visiting Ireland sometime in June, 2015 and it would be nice to connect with my roots. Any information would be appreciated. Thank-you. Regards........Wayne Alan Skelley,
