Dear Eleanor,
What an amazing discovery about your family's past (and potentially, its future)!
As you certainly know, there have been many times in Jewish history when we have needed to disguise or deny our identities in order to survive. As a rabbi who runs a program for people converting to Judaism, I have been overwhelmed by the number of stories, like yours, of people who rediscover Jewish roots in the most unlikely of places. I am moved by the fact that quite often these people report that they have felt a life-long affinity toward Judaism, even if they couldn't place its source. I believe that our hearts know things about us that our minds often do not.
I encourage you to learn more about Judaism, so that you can gain an understanding of the customs, traditions, and practices that your family carried for many centuries. You can do this for signing up for a class at a local synagogue or Jewish community center (if you are in Southern California, I encourage you to check out the
Miller Introduction to Judaism Program, which I run). There are also a great many website (one of the best is
MyJewishLearning.com) and, of course, tons of books. You can check out a good list of suggested reading by clicking

In the end, your decision about whether to embrace Judaism as a new spiritual path for you, or to retain your Roman Catholic traditions with a new and deeper appreciation for your cultural roots is a very personal one, which doesn’t need to be made now. Beginning with learning is always a great first step.
I wish you great inspiration as you seek, and offer blessings that you find meaning in the answers that you receive.
