[Harry Potter] Will the Marauder's Map use a deadname?

So, I'm trans, and I've had my name legally changed. Nobody uses my birth name, and the only people I really associate with that knew it were all family/hometown friends. 

If I'm seen on the Marauder's Map, though, will it display my deadname or the name I go by?

Well, given that Fred and George never commented "Hey, look, Quirrel's dot has "Voldemort/Tom Riddle" overlaid on it, it probably works off of your current name. Or possibly whatever you're enrolled at Hogwarts under. It's not a very well explained arcane artifact.
