Welcome relative probable relative. A Gustav and Wilhelmina Taube ended up in Geneseo, Illinois. I believe they ended up having a family of seven boys and several girls. Gustav became a railroad worker and died of pneumonia contracted while working on Christmas day.
My father, Arnold M. Taube, wrote a family history in the 1980s that contains some of the same information you list. I have photographs of them, digitized, as well as an electronic copy of my father's draft of a Taube family history.
My personal email address is:
Taube@Geneseo.net. Send me your email address and I will forward a copy of my father's family history.
