Costello family County Carlow

Hello,

I am looking for Costello Family in County Carlow. Great Grandma came to Canada then to the US. Her name was Margaret Costello. She married a Murphy from Cork. His first name may have been John or Dennis. Margaret was born in 1872 but we are not sure when she left. Family history says something to do with Easter Rebellion. If anyone has information about this family or Murphy family in Cork (so many Murphy's not sure where to start) please contact at ckucinski@earthlink.net. Thankyou.
