John L. Rademacher had 6 sons and 5 daughters. The one you are referring to is my great Uncle Jack. I am Jerome (Jerry's) and Dorothy's granddaughter. My dad is also Jerome (Jerry), but a lot of people in the family know him as Zeke. My e-mail is firstname.lastname@example.org
I'm guessing that you are not Kim Rademacher (but probably a sister-in-law) who is also looking for info.
