So both your parents were indeed born with British citizenship - you will know this being so glued up on history.My father was born in Tipperary in Newcastle
My mother was born in Dublin
They were born Irish in the 20s, only just in my father's case.
I went to school here as my mother wanted us to go to Oxbridge or the Royal Academy.
I read Classics at Kings College, not Oxbridge I hasten to add, my eldest brother told me he'd break my legs if I applied. My sisters had not had a happy time of it there.
So I decided not to apply to Oxbridge and it worked out well as my father became ill and I was needed at home so worked 3 jobs and did my degree and was the only undergraduate invited to work on the porphyrogennetos project which was an incredible experience.
You were born in England as a British citizen. You went to a British school - despite previously saying you spent most of your childhood in Ireland. You went to a British university. Your parents lived in Britain for more than 20 years. You and your siblings have lived in abritain for most of your lives.
You don’t come much more British. You are more British than Irish. If you want this collective British guilt then you are part of it.
