While traveling last week, I received another set of articles from researcher Denise Anderson-Decina in Indianapolis. Below is a copy of the death notice for my great-grandmother Blanche Lamon O'Brien. The first is from the 12 February 1976 Indianapolis News.

The notice mentions that Blanche was a former matron of the Millersville Order of the Eastern Star. The chapter secretary is currently checking their records to see what they may have on this. According to Wikipedia, the Worthy Matron is the presiding officer of the OES Chapter.
