Byrne/Kelly Families of Ballymacward

I am interested in finding out any information about my great-grandmother Bridget Byrne's family. I believe that she was born in January 1874. Her parents were Patrick Byrne and Annie Kelly.  She emigrated to the US by herself in 1895. We were told that she was sponsored by her mother's brother Martin Kelly who had moved to Boston sometime earlier. I have seen the Byrne family listed on both the 1901 and 1911 Irish censuses living in Liscub East. The names of the family members are the same names that we were told are her mother and siblings.I visited Ballymacward myself in 2006 and saw the Byrne family plot in the Old Cemetery. I believe that the Patricks on the headstone are my great great great grandfather and my great great grandfather (Bridget's father) but I could be mistaken. I have not had much luck finding any records pertaining to anyone other than the census records and Bridget's birth record. I can find no records that indicate that there were siblings named Annie and Martin Kelly. Any help would be appreciated.
