Your initial request was too brief. Your replies are still far too brief for the likes of me . Might I suggest you put aside your ‘informant’ and really welcome further help being offered. Because this is my last effort for you.
I made a mistake jumping on the May family suggestion, instead of absorbing your 2nd reply saying O’Neil of Rathfriland is what you are trying to find out about. Yet you knew about May’s!
So extending the unthanked sensible reply from whiteout7 on Ros Davies website
{which has loads of 'little'}

Miss Mary O'NEAL . Drumgath regd. Rathfriland; wife of John Grant; mother of John b. 1874 CR
Searching to church records for Co down relevant parishes for catholic records. Here is my starter from two sources
1. Ros Davies website

Barnmeen Catholic Church- St. Colman's

This is the oldest Catholic church still in use in Dromore Diocese.
graveyard purchased mid 19th century; prior burials in old graveyard
2. PRONI you need to download Also this doesn’t seem to cover all of Ros Davies listings so I have missed something.
