On behalf of Jews everywhere, Jocelyn issues the formal welcome:
I am David's wife and he has been forwarding me all your email exchanges. We are fascinated by your story.
So... now that you know you are Jewish, has anyone yet taught you the word mishpochah? It means family, and it can mean your immediate family or the Jewish "family" as a whole.
So I say to you: Welcome to the mishpochah!
(yes, French first name, Scots last name, and I am a Hoosier by birth.
And Jewish. We are everywhere.)
