Give the details here in the thread. Trust me nobody but you is going to know it's your wife unless you share pics. Even if you were to use her real name and location do you have any idea how many Sean Renauds there are in your city? Now you shouldn't do that, use a fake name and unless the city is important (obviously you can't visit Lady Liberty in New Orleans) pick a city on the far side of the country from you..
Otherwise the more details you give here the more likely you are to get a story and if you're lucky you might get multiple stories from multiple authors who all find your idea to be fun. There is no upside to privat messaging.
