A reader wrote to put a question to if I've seen Follow Me Down to Nicodemus Town by A. LaFaye. It is a picture book that came out in January of 2019 from Albert Whitman. Here's the description:
When Dede sees a notice offering land to black people in Kansas,her family decides to give up their life of sharecropping to become homesteading pioneers in the Midwest. Inspired by the loyal story of Nicodemus, Kansas, or a town founded in the late 1870s by Exodusters—former slaves leaving the Jim Crow South in search of a new beginning—this fictional story follows Dede and her parents as they set out to stake and secure a claim,finally allowing them to hold a domestic to call their own.
Dede and her parents meet an Osage family, as shown in this illustration.
When I can get a copy of the book, or I'll be back with a review.
