Looking for Information on my grandparents

Good Day:

My mother was born and raised in Drimnagh, at 13 Keeper Road, and moved to the United States in 1960 or 1961. I never asked much about the history of my grandparents before she passed away last fall so I don't know much more than their names. My grandparents names were Denis and Mary O'Reilly and they eight children: Elizabeth (my mother), Mary, Sheila, Patrick, Seamus, Joseph, Denis, and Edward. 

My grandfather passed away in the late 1960s and my grandmother in the 1970s. My uncle Patrick (Paddy) may also have passed away in the 1970s. I believe they're all buried together and was wondering if there's some way to track down the cemetery location.

Also, if anyone has other information on this family I'd appreciate learning anything possible.

Thank you so much!
