I'm from Belgium and it is a typical Dutch name (Netherlands or Belgium). His name's history indicates the place you originate from, like you have d'de in French.
About the pronunciation, you can't make a big mistake. You will herehear a slight difference when hearing it from English, French or Dutch speaking people (French speaking people won't pronounce the ending "e"“e” as much as f.e.for example Dutch speaking people).
But overall, as long as you put the emphasis on the "mon"“mon”, you should do fine.
