First off. Marietta is my favorite from your list. Speaking of, there are a few issues there. Let's address some, yes?
Marcie- not classic, it is a nickname
Mystique- also not classic, rather new as far as names go
Marjerine- a butter spread?
Marselle- this spelling brings up Marseille (French town) on a quick web search. Marcelle on the other hand is a makeup brand.
Marjoram- an herb, not really an appropriate name for a child
Makepeace- where did this even come from? It sure as heck isn't 'classic'
You know what, in case you didn't know what classic meant, here you go from our good friends, Merriam and Webster
judged over a period of time to be of the highest quality and outstanding of its kind
