Sylvia Jane Bailey Morris Stewart

Wrote an earlier message sometime back on this woman. She was born in Dent or Webster county in Missouri, a daughter to James Marion and Mary ELLEN Bailey. Have found her family background, but I can't find her whereabouts once she lived in KC.
She was married at a very young age(13) to Arthur Morris, became a widow and married his brother George Morris in 1920 at age 18. In the late 20's and three sons later, she left them and moved to Hutchinson Kansas. Leaving out a lot of details here, she then married a John Stewart, but left him, and supposedly went to KC.
I wonder if there were any relatives there she may have moved in with for a while? She did housekeeping for a lady on Holmes Street off and on. She may have worked at the GENERAL HOSPITAL in the 1950's. I don't know where she died and was buried, and not even when. My guess is she probably was poor.
I don't know where to begin to look. I have tried, by calling, a few mortuaries and a couple cemeteries in the downtown area around Cherry Street, where she may have lived.Does anyone have any suggestions on how to find her?
