As for her, her father could have been acceptably "Jewish" to Orthodox Jews, through genetic linage of grandmothers, even though not observing Judaism, but she would not be recognized because her mother isn't Jewish. Reform Jews would only recognize her if one of the parents were an observant Jew. So she wouldn't meet the criteria to most religious Jews, but she could still be considered "ethnically Jewish" or labeled so by distant heritage. Considering she has east asain dominant features, most people would not consider her a part of the big club.
