Fascinating - she has a fairly unique name, but there appear to be 2 of them - one born in August - one born in June and married into the name. Noting this so that they're not confused with each other. The other one (not your Mildred) has the following records:
"United States Social Security Death Index," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:J5H8-V3R : accessed 29 March 2016), Mildred Blaue, 08 Aug 1995; citing U.S. Social Security Administration, Death Master File, database (Alexandria, Virginia: National Technical Information Service, ongoing).
"Find A Grave Index," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:QVLC-XFCP : accessed 29 March 2016), Mildred C Blaue, 1995; Burial, Wellsville, Montgomery, Missouri, United States of America, Wellsville Cemetery; citing record ID 88428172, Find a Grave, http://www.findagrave.com.
So while I don't have an answer as of yet, I just wanted to point out that Mildred G Blaue is definitely not the same person as Mildred C Blaue.
