I think I remember seeing information for Augusta.
In later records I find Caroline Goecks and that is how it was spelt in our family. I have seen a lot of names in the Germany listing having it spelt Jaeck and Jaecke.
I have mostly just started scanning whole census records for the townships that they could have lived in to find them. Oconomowoc Township is very difficult to read and I have a feeling that's where Michael and Caroline lived in 1880. Lebannon is not that far so somehow we are probably connected. Have you figured out where any of this family are buried? Michael died some time between 1870 and 1900. Caroline is living with family as a widow in 1900. Lori
