Looking for a Cemetery in Drumreilly

I will be visiting Leitrim in May and would like to find my ancestors graves. All I know is they lived in Drumreilly Lower Parish, County Leitrim. I know my 2nd great-grandmother died 10 Mar 1889 and my 2nd great-grandfather died before that. My 2nd great-grandmother on the other side of my family died 15 mar 1864, also in Drumreilly Lower Parish. That part of the family lived in Gleb. I think the other side lived in Bawnboy. They were Roman Catholic. Can anyone suggest a cemetery where I may find the graves and is there some way I can locate the graves online before I go to Ireland? (I'm a dreamer!!) Is there a way to find the graves once I get there?? Another town (townland??) name I have is Clendargan. I know I'm grasping at straws here but I don't really know how to ask this question. The family names I'm looking for are Fox and Smith.

Thank you in advance for any help.
