Hello, my name is Meleah Jahnke. I am 21 years old. My gpa's name is Al Jahnke. I don't know really anything about my Jahnke's side of the family. I was reading your thread and your looking for Jahnke's in Wisconsin. All of my family lives in WI. So I don't know if you know any history about Jahnke's, but I'm curious.
