This. Very sorry for your loss. Just be there for her family as best you are able. Even if they're hardcore Orthodox Jews, btw, they will neither expect you to observe esoteric mourning rites, nor get mad at you for violating such. Offering your condolences and your presence will be appreciated a lot more than would an awkward attempt to observe your best guess at the proper Jewish customs.
