Goodness me!
So far two folk have misconstrued my post and both are sceptics. 
There's nothing wrong with having Northern Irish roots nor do I think there is anything wrong with being Northern Irish .
I said all bar one of my great grandparents were from Northern Ireland which means all my grand parents and my parents were Scottish so I am clinging to the one Scottish ancestry thread I have, as I feel Scottish not Northern Irish.
As I said, it doesn't really matter, does it? Over time immigrants do identify more with their country of birth than with the country their ancestors left. My husband was the product of a 'mixed' marriage. His Protestant paternal grandmother wouldn't let him or his siblings into her house, although they had relationships with their paternal grandfather outside the house. Consequently his upbringing and influences were Irish Catholic. He identified himself as English, nevertheless.
