Christopher, were you up late on Paddy's night?

The Colls were all Catholics, so yes, I think I need to rely on Church records.
One definite fact I have is that there were descendants in that area called Joe and Nellie Coll who were brother and sister and they lived in the St Mary's Hill area/road. Cloonlateive is the area that my cousin remembers from his parents where the Colls came from.
And yes, here's hoping that the church records still exist.
Does this ring bells out there for anyone?
Regards - Ursula
