std::map::find expects to be passed the key.  This means that I would
have to pass myMap.find(std::make_pair(givenName, ???));

Since the second parameter is compared this needs to be some value that
std::map::find knows to ignore.  If I could do this I wouldn't be
trying to code my own comparison.
