Marie Claire was an established pianist and the 14th Phantoms wife.

She was a quiet in the background type of wife unlike her mother in-law. Assuming she was from France as the 15th Phantom studied in that country as a youth.

Not much is known about her life. She did die a few months before the 14th which was a painful year for the 15th.

She was buried in Paris and not the grove outside the Skull Cave were past Phantom wives were buried. One of the few that has been shown buried.
