It has been almost 7 years since your post, but I just stumbled across it. My Grandad was Glenn Marion Piburn, also son of George Marion Piburn. I didn't remember how his sister's name was spelled. We are the same family. Glenn married Augusta Maxine Jones from Dearborn. She went by Maxine. They were my "Granny and Grandad" and lived in Gladstone, also in Clay County, MO. They had two kids, Patricia (Patty) and Russell (Rusty). Rusty is my dad.
I can probably come up with a lot of information/pictures of the Piburn family. George Marion Piburn was "Pop" Piburn to my Dad.
