One of the plot devices in a story I'm writing involves someone having a secret marriage (in the US) that no one ever finds out about by normal means. But on top of this, the person that is involved is someone famous. Like for example, say the mayor of a town for 20+ years has been married to someone but the arrangement was kept secret. Do you think this is plausible that someone famous could go 20 years without anyone ever finding out? I imagine if someone looked hard enough they could look up old marriage records, but those records might be hard to come by and the people looking might not know what they are looking for. I was thinking it might be impossible to keep this a secret because you would think that some random reporter at some point in time would do research on this famous person and stumble upon the fact that he's married and that would be the end of the secret.
