I'm inclined to agree with the idea that there are trust issues you should work on, but I don't want to give any advice about that; I've never been married or engaged, so I can't pretend to truly understand what that kind of commitment means.

Here's a sneaky idea: after the holiday, bring up to your fiancee that she looked uncomfortable around your family. Say that you saw something in her body language. Never bring up the fact that you invaded her privacy. Use this lie of a physical tell in her body language to bring up a discussion on how she feels about your family. Tell her to be honest, that she can be honest with you.

If she lies to you then, well, then you might have to re-evaluate things.
