On Kirby Ross website Civl War St. Louis there is a story about Elijah Alexander Mays. Mays was captured by the Union and made to work on earthworks and then sent to prison and never made it home. Mays land was in the same neighborhood just a couple miles south of 21 and HH Junct.
Here is a link to that story
