Ireland is already in the EU, and has been an independent country since 1921. The Republic of Ireland.
There is a chunk of that island though that is part of the United Kingdom country, called "Northern Ireland".
The "Ireland" and "Irish" in question being talked about by anyone in regards to the Brexit... is Northern Ireland, not the Republic of Ireland.
Though it's not impossible any Irish ancestry you have is from Northern Ireland I suppose.
