Eligible for Irish citiz. with father born before Dec 1922 in Northern Ireland?
My father was born in Northern Ireland before 6 December 1922. I was born outside the island of Ireland. My father never made a declaration of his Irish citizenship. He held the UK passport and then became US citizen before I was born. Can I apply for Irish citizenship on the grounds of my ancestry (or other)? Can my children apply?
Any help is highly appreciate. Thank you.

It appears you're already an Irish citizen => apply for an Irish passport if you want one.

Your children appear to be eligible to apply for Irish citizenship by Foreign Birth Registration.
