Greetings... I am not related, just trying to help.
Is it possible that Alice got remarried?
I found a death certificate for an Alice Robinson:

If you'd like this death certificate, go here:http://www.sos.mo.gov/archives/resources/deathcertificates/#...
Enter Robinson, Alice, Buchanan Co, 1918
Click on the View Image button... it will be an Adobe Reader .pdf file (you should have Reader on your computer, it's pretty standard).
Hope this helps :)
