Ethnically Jewish.. Culturally Not

Hello. My maternal grandmother was Jewish. I did not get to know her well, as her relationship with my mother was strained. My mom grew up with her paternal grandparents, who were not Jewish. My grandmother has since passed, and I wish I got to know more about where our family came from and what it means to be Jewish. I remember a few times early on in life when we did see her. She wrapped a prayer shawl around my cousin and I and read from the Torah. I have her Torah now, and want to be Jewish. It’s hard because I live in Oklahoma/Arkansas and there aren’t very many places to immerse myself in Jewish culture. Any help would be appreciated!!
