I too know of Mr. Kettering. But I am not related to him.
I was typing up all the notes from my mother in laws records today and ran into the Kettering name. It seems as tho The Ketterings were family friends to her family. I can type up the story she wrote about him, if you'd like.
Her name at the time was Edythe Beard and she lived in St. Petersburg, Florida. This was oh I'd say in the early 1900's. She was born in 1911, and she states that she was just a baby.
I was just wondering about him, so I thought I'd look to see if I could find anything on him. And so I did.
