Welcome to RootsChat, everybodyscream!

Just looking at this, and I'm not familiar with what I assume are Irish records, if the names of Michael Hegerty and Patrick Leonard (assuming forenames from the abbreviated versions written in this record) are both male, so it seems likely that they were witnesses, Patrick being a relative of Mary Leonard. BUT wait a minute - is the abbreviated name Patrick or Catherine? Not sure, even with comparing similar characters. And the names of Michael Hegerty and Patrick/Catherine Leonard are written twice, so were they witnesses or partners at each other's weddings?
The indentation of the lines seems to indicate a new entry, and the initials (?) at the end of some of the lines are those of the priest or parish clerk, maybe.
Sorry for this rather woolly reply, which doesn't seem to be very helpful, as it raises more questions than answers.

Others will be familiar with Irish records and may be more helpful to you.
