Cousin Jack. He is so missed. I’m gathering information for a family history project and came across this. Footage of my family VHS tapes and our photographs are included in “I Don’t Know Jack” movie. A snippet of my mom and I are actually in the trailer – that’s me standing next to the Christmas tree with my giant title wave bangs. My grandmother and Jack’s mom, Aunt Ag, were sisters. So, Jack is my mom’s first cousin. My mom, “Baby Ag” was named after his mom, because she was born on her birthday. I always looked forward to Jack’s visits to Texas because I knew I’d get be up all night with the drunk adults listening to his stories.
