I think I might have Patrilineal Judaism?

Hey everyone, I’m 20 (F), and I was talking to my aunt on my father’s side. I asked her if we were Jewish, and she said that we had Jewish cousins that my Grandmother and Grandfather would visit, but a lot was done to remove that…I don’t know what this means… I work at the Hillel Center near me…Would it be beneficial if I asked my friends there about this? I’m so confused, any help at all would be appreciated! Thanks in advance
