Yes, you are definitely related to my husband, Kevin.
He is the grandson of Eugenie Theresa Oelkers, sister of Joseph Robie Oelkers.
Kevin's father is Arthur Oelkers Schott. He is 92 this year and will be interested when I tell him about you.
I would love to share information. I have a short autobiography written in 1916 by John Henry Oelkers.
