I just found out I have jewish ancestors

Uhm, so I know I cant claim I’m jewish because my mother wasnt raised jewish, but both sides of my family are jewish. I was raised catholic, and I was told at a young age that my great-grandpa fled germany to come here with his family but I was never told why. When I did some digging into my family history recently, only then did I realize the actual reason he fled germany was because he was jewish, and so was his family, and they had escaped the holocaust and came to america, completely changed their identities, and their kids later became catholic (like I was previously, no longer practicing.)

Then I learned from my grandpa on my mothers side, that his parents also escaped the holocaust and fled to America, doing the same thing as above.

I don’t know where to go from here, because both sides of my family are jewish, but I wasnt raised jewish, and neither was either of my parents. I want to be able to connect to my family, and my ancestors, this is so important to me. I know I probably shouldnt be asking for advice for a topic like this since its dark, but what can I do? Im a female, I want to be able to connect to my family, but I don’t know where to start or if I even can. I feel like a huge part of me was stolen, and I cant do anything about it. My dads side is jewish and so is my moms.
