It was just a matter of time until Ancestry joined the party with their indexed versions of Catholic Parish Records.
Here’s a link to their announcement: http://blogs.ancestry.com/ancestry/2016/03/01/largest-collection-of-irish-catholic-parish-records-launched-online/.
The Family History Library also offers free webinars, and one way to celebrate St Patrick’s Day this year is to listen to one of these YouTube courses:
March 17, 11 am MST Where is That? Finding and Understanding Places in Ireland
March 17, 1 pm MST Ireland Census and Census Substitutes
March 18, 1 pm MST Irish Protestant Records
