You might recall seeing Ginette elsewhere on the list, where she was paired up with her granddaughter Ismaelle. She liked the portrait so much that she came back to Colette for another one, this time with her son Mathieu, who is Ismaelle's father.
There's very obviously a strong set of genes in this family. Ginette looks even more like her son than she does her granddaughter, and that's despite the fact that Mathieu has a beard. If Ginette ever went out disguised as a man, this is what she'd look like!
