Re: Nockarne, Queens Co.
You can use this site to get a list of all the townlands in Queens County. The townland was what most Irish people used as their address.
The “Nock” bit of the place name will be Knock. (Knock is the Irish word for a hill). You’ll need to look at the options for the one that sounds most like Knockarne. Knocknakearn seems the closest, but I could be wrong. You can find it on Google earth, near Portlaosie,, Co. Laois.
