A John Schasteen (b. ca 1875) md. Lulu Catherine "Kate" Newton and is listed in the 1920 census of Jasper Co, MO with his wife and mother-in-law, Sarah Philips Newton.Also, two children are named: John b. 1903 and Besse b. 1907.
I also found a WWI registration at ancestry.com that listed a John Harrison Schasteen, age 44, b. Sept 5, 1874, living in Colorado Springs, Colorado, and his nearest relative was Mrs. Kate L. Schasteen.
I cannot find census records for this John Schasteen after 1910.
