Rosehill132 rootsireland doesn't have the original certificates, just transcripts.
You should be able to find the civil registration certificate which would give you both father's names and occupations plus maybe a more accurate address at time of marriage. You could search for that on the Irish civil registrations on
www.familysearch.org or if you have a subscription to ancestry.com or .co.uk they have civil registration too. You are looking for Mary Cooney & Joseph Kelly who both have the same page & volume number.
Alternatively, you could write to the G.R.O. in Roscommon and give them the info you have and they should locate the cert for you for a small fee.
