There are few existing courses from Southern Indiana that fit the timeline. New Albany CC was built in 1922 I think, but was only nine holes. It's certainly possible that the Jeffersonville CC could have used this site. Probably unlikely.
Maxwell did a course in Louisville right? I think you uncovered that article if memory serves me right. He was from Princeton, KY and did a few courses in Western Ky as well as doing green work at the Lincoln Homestead course.
