Hello. I am Royalty by blood line.
My ancestor were both John O'Neill (the first King of Ireland) and Hugh O'Neill (the last king of Ireland). The rights of Royal Handover were in a direct line of the O'Neill family as far as I know.
The O'Neill family are the longest living family in Europe apparently, but the Irish Monarch were forced to disband because Parliment in England thought at the time we were trying to over-rule them. I think it was Queen Elizabeth the 1st who made the final decision to force us to renounce. Not quite sure on the ruler, but it was around the 1816 era.
My dad had met Princess Anne over the debate, but it was not publicised.
