I may have found what you were looking for in the Drouin. I found the marriage of Joseph Vezina and a Ayet Malo in St roch de L'Achigan, but the name isn't listed as Vitaline - it is Anathalie - who happens to be the daughter of Gabriel & Monique Raymond. So if this is the same person as Vitaline, and I can't imagine that it isn't, then she is the sister of Narcisse.

If you email or post back, I might be of better help sorting this out.
