PRONI is a must stop for Ulster Research!
I had another opportunity to visit the Public Records Office of Northern Ireland in a recent visit to Belfast. I have had great success finding records on ancestors every time I've been there. And when you find out the vast number of records archived there, you'll understand why it's must stop in Ulster and Northern Ireland research. Heading to their web site is a great place to start. https://www.nidirect.gov.uk/proni.
