Do you mean like Marie-Laure or Anne-Marie?
I happen to adore double-barreled names in general, and Frenchified combos are my favorite, so I would say they are usable for sure. As for being in style, I am not sure. I guess it would depend on the combo you chose.
You could certainly use a name like Yvonne-Jeanette. However, since both choices in the combo are a bit dated, the overall feel is dated as well. Usable, but not on trend. Carole-Anne might do the same thing.
Alternatively, you could go with something similar but more updated, such as Callie-Ann instead of Carole-Anne.
I personally think unexpected combos like Eva-Martine, Stella-Faye or Tansy-Bette are the best options, but those that use names that are in style right now work well too (think Lily-Belle or Harper-Mae).
Anna Kathleen is quite pretty too.
