As the matriarch of the Barone family. Robert often refers to her as "Queen Marie". Even though her sons are in their forties, she still coddles them like little kids, but she has always favored the younger son Ray over Robert. An exceptional cook who always keeps a clean house, Marie often criticizes Ray's wife Debra for not keeping her own house clean and feeding her family properly and she dismisses anyone who doesn't live up to her standards. Even though she loves Frank, she constantly bickers with him and calls him a lazy, stubborn slob.
Marie has a habit of making someone feel guilty in order to get what she wants. Most of the time, the person that she makes feel guilty is Ray.
