Eoghan is also lovely and love the traditional spelling. I would advise against Éire. I wouldn't recommend your child ever visiting Ireland with a name like that, it would be seen as a joke.
Its very much an 'American' name rather than a name any Irish person would use.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
