You have found the same records that I have. Liza can't be her nickname because Liza marries someone else. The other possibilities die at the wrong time and John Boucher the possible father is ruled out because it states he was born in Tennessee and on the 1880 census, Jugertha says that both her parents were born in Missouri as was she. Mahala J. was another person I looked at strongly since she has a J. for middle name. However, she dies in 1886 and Beulah is born in 1891. I would have loved to see an 1890 census, but it doesn't seem to exist. Thank you for all the time you put into this. I wish you had found the smoking gun, but seems to confirm I have found all the seemingly available documents.
