Oh how wonderful. I just adore Stephanie so the idea of her becoming a doting grandmother is terrific. What is Marie's background? Is she an American? I don't think I know anything about her.
Not much is known of her. She met Louis at a university in the USA, some sources say it was in North Caroline, some say it was in California. her roots are Vietnamese/French, maiden name: Marie Hoa Chevallier. Sounds like a Vietnamese/French marriage of her parents. She is presently working as a project manager in Monte Carlo. All sources, and they are not many, claim that they met in the USA while attending the same university.
But everything else, her parents, siblings etc. are not known.
