One option might be for the real Sean Byrne to move to the address in Sligo of the fictitious one, then ask to be removed from the Entity List on the grounds that he is a real person. I think that wouldn't work, and could be life-changing in a bad way, but it's an idea.
It might result in his address and birth date being added to the entry on the Entity List, now that the authorities have gained knowledge of that additional information. ;)
