My great great grandmother was Augusta Jaecke (pronounced Jack-ee now but at earlier times Yack-ee). The family lived in Lebanon, WI. Their name has been spelled many, many different ways, but I haven't seen Goeck(e) yet. Surprisingly I found them in emigration records as Jaecke in 1848. After hours and hours of searching, I found them in 1850 with the name spelled Gaher, in 1860 Yacher, and 1870 Yackya. On a few court records, the name has been Yakie and Jacke.
