From day one, I wanted Chloe to have a big brother, although I never managed to settle on a design for him. Let's hope this current version sticks. I actually asked my father to pick a name for him.
- Frédéric was named after Langelier Blvd., which runs between the neighborhoods of Saint-Sauveur and Saint-Roch in Québec City. The street was in turn named after François Langelier, mayor of Québec City from 1882 until 1890 and lieutenant governor of Québec from 1911 until his death in 1915.
