Hi,
I have an Elizabeth Keogh in my family tree. My g-g-grandmother was Elizabeth Keogh. She married a Patrick Dillon in @1850-1852, so safe to assume she would have been born @20 years previous to that. (I haven't come across the birth or death record yet)
They lived in Ballybarney, near Calverstown, which is no more than 5 miles from Kilcullen. I know when I was looking up the records there were a lot of O'Neill's as witnesses, etc., on my family tree records. I couold dig them out and have a look??
Not sure if any of this helps or not.
Maureen.
