I live in Virginia, but my parents (Mom 82 and Dad, 84) live in Negaunee. Dad is the oldest child born to Juha A. Kallioinen, but my Mom has done all of the research on both sides of our family.
Mom was extremely interested in the information you had posted. Most of the older generation has passed away, and she didn't know of Tekla. However, I would guess that she would be interested in meeting your aunt. And yes, we would be interested in seeing what other info you have assembled.
You never know when you might find another puzzle piece!
