A new Jew looking for advice

Hi all-posting here as someone who is new to both Judiasm and reddit.

I was adopted at birth and it was not until I was 30 years old that I learned I was Ashkenazi after taking a DNA test. This was last year. I have no identifying information about this part of my family. His name does not even appear on court records because he was not informed of my birth or my mothers pregnancy.

I have been trying to process this new information and discover what it means for me. I was raised in a Christian family (Mom sang in church choir, Dad was on all the volunteer leadership committees etc. etc.) and the faith of my parents is still very important to me while my own religious leanings are unknown to me at this time.

Being Jewish (small j? Big J?) is the first thing I have ever experienced where I belong without someone having to make a conscious choice to accept me (so far as I understand Judiasm). I am looking for concrete ways to be more active in discovering this previously hidden part of myself. To be honest I am not sure what I am looking for or what I want but I am very excited to start looking.

Any advice, practices, resources appreciated!
