Maybe. Go to a beit din and make them do the archives. It happens alot today, 10 stories off the top of my head where people who thought they weren't Jews get into Judaism. Funniest I know an Arab in Israel wants to convert, pushes his wife to do it to and turns out shes already a Jew and he has to separate from her till they remarry.
I know I'm a Jew and still did the whole archives thing, they didn't really bother going past a family member who was a leader of the resistance in France, because the Nazis needed her to translate and she demanded to write she was a Jew even if it meant they had to do lots of paperwork all the time to keep her from being murdered. My grandmother remembers eating papers as a little girl and delivering baskets with fruits on top and papers on the bottom as a little girl. Really wanted the whole family tree but whatever they find one indisputable proof they sign and it's over, you have to pay certain genealogy societies for the whole tree.
Lol imagine you're her tikkun (repair, redemption, measure for measure correction) and Hashem really wanted to pull it off like this that the great grandson of an apostate hates what she left for. Could also mean nothing, but like worth a little investigation. Ride your emotions like a horse, it's much more comfortable than lying there while they trample you into the dirt. Hearts are valiant enough to do it. Make your brain useful to think of ways to keep you on the emotional horse instead of worries about the danger of equestrian activity.
If you are a Jew and therefore considered a child captive at birth, then if you kept the Noachide laws you were righteous in your life. Either way it's still you, maybe you can still eat your pizza, not that I can't make better with beef and hemp cheese, maybe you need to be more focused on not letting the tefillin touch the ground. Lol be happy at least your life isn't boring.
