I am not sure how much help i can be. I am 22 years old. My last name is Walkenhorst. My dad is Lynn Walkenhorst. His dad is Vernon Walkenhorst. I am not positive, but i believed my grandfather (Vernon) lived out in the Midwest (ie Missouri, Kansas, Missippi, etc.). I currently live in San Diego. Let me know if any of this may help you out.
