Seeking information on the Charles Quest family who lived in Butler Co. Kansas 1870-1920?

Charles and Martha were married in Illinois December 23, 1866, and they are found on census records in Butler Co from 1875-1920.
I have records on their son, John Monroe Quest, but not on his siblings or his fathers parentage.

Any information would be welcome, and I would love to share information with someone on this family!

Thank you!
Laura
