Hi Joanne,
I looked at your tree real quick and your oldest Sommerfeldt was born about Johann Christian 1843 and looks like your family settled in Minnesota.
My Michael Summerfeldt was born earlier.
Very family names - like Henrietta Krenz to my Mathilda Krenz who made the son of Michael whose name is Julius.
Diane - you can write me at deedeerossell@yahoo.com if you think we have any chance of being related. Mine all were in Wisconsin.
