"My great-great grandfather was August Wilhelm Herman Voeks ... He was married to Johanna Kruger and settled in the Milwaukee area."
In case it's helpful to your research, there are multiple family death notices in Milwaukee's German newspapers for an August Voeks (80 yrs.) in 1909, and a Johanna Voeks in 1900. There even notices in 1859 published by a Friedrich Vöks warning businesses against granting credit for purchases made by his wife Mrs. Maria Vöks!
