I recently found out I have Jewish ancestry through a DNA test (Ashkenazi; it helped to explain why I got bowel cancer at a young age since the risk is high in that group). Apparently my grandmother knew, but didn't tell my father. Previous to this, all my Jewish ancestors were open about their faith. My father and his siblings were not raised Jewish, but were socialised with Jewish children. I suspect my grandmother was keeping this a secret from my grandfather who was an atheist, but still had a desire to pass on something, or at least raise her kids so they weren't anti-Semitic. Whatever the reason, I feel a bit sad that this heritage was lost, and would like to know more about Jewish history, culture, and religion. I'm not interested in converting.
After some digging, my father and I found out that our original Jewish ancestor was kidnapped by the British navy in the late 1700s and pressed into service. He escaped to Canada a decade later and never returned to Britain. It's a shocking bit of history. (In an interesting coincidence, as a Canadian immigrant to Britain, I now work a five minute walk from where he lived in London as a cloth merchant.)
I've been learning more about Jewish history in Britain specifically, but most of what I've been reading has been academic. I'd like to connect to the Jewish community here in order to learn more, but I don't know what's an appropriate way to approach it, or where, who, how, or even if I should. Any suggestions or advice?
