Because my Mom was born in Ireland,making her an Irish citizen at birth.Under Irish law anyone whose mother or father was an Irish citizen when he/she was born in also automatically an Irish citizen regardless of where he/she was born.
Until fairly recently Ireland had pretty "liberal" citizenship laws.
But,as I noted,I've lived in the US for my entire life.
