Paternal Greatgrandparents and earlier

My Greatgrandparents - William Carroll and Anne Wilson were married @ Clones on 21 July 1855

WC was 30 and a farmer at Cappagh, Parish of Clones and his father was Thomas Carroll also a 

farmer at the same location. AW was 22 and from the same location, as was her father who is 

described as an Agent. I believe they may have been married  in the parish church of Clones.

I also understand that her father and mother ( Anne Elliott ) we're also married in Clones in June 1815. 

Any further information you can provide will be greatly appreciated. Thanks
