The Gustafson's of Genoa, IL

I have just started researching my family tree. We know very little about the Gustafson side of our family. My great grandfather, Daniel, left his wife Mary Electa in Sycamore, IL. We beleave he moved to Iowa and started a new family. His son Berton was my grandfather and his son Morris Jabez was my father. My father died in 1979.

Any information that you have about my family name would be appreciated. I am willing to share the information that I have gathered so far.
