Yes, we are related. Loretta is my mom. My dad, George L. Kadar, SR. died in October, 2004. Joe (your grandpa) was my mom's beloved brother --her favorite. Your dad, who I called "Bernie" when we were growoing up on 138th St, in Blue Island, was always a very sweet cousin. Your research sounds correct as far as it goes.
I'm attaching a 1980's photo of me, my two sons (Justin and Blain), my mom, and Grandma Glim. My mom is still alive. If you'd like to stay in touch, you can e-mail me at
