My husband discovered years ago when the bum bailiff turned up, that he and another baby boy born 3 minutes apart at the main hospital in Copenhagen had been registered and baptised with the same first and second Christian name and had the same surname. Their fathers had the same Christian names as well, and were not the same person. Being born only a few minutes apart they had consecutive social security numbers with only one digit's difference between the two numbers.
So he could prove he hadn't defaulted on payments, as the social security number on the citation was not his.
Perhaps OP's finding was caused by something similar.
A quote for those blessed with a spouse:
Soops kitchen, a place of reflection, refuge and at times revelry.
