The reason I'm calling it out today, is to direct researchers to Joe's most recent post, the Online U.S. Catholic Parish Registers 2017 List. This up-to-date list follows a series of major announcements about new RC records collection releases in the USA, and sets out the parishes, regions and dates for the records now available to family historians. It's just begging to be bookmarked by every genie with Irish roots, no matter from which side of the Atlantic (or any other ocean) their family may now hail. See the blogpost for further details.
Big thanks to Joe for creating the list!
