UPDATE: Thanks to Intense Guy, we have some biographical information about Minnie.
Minnie Gurr, born in 1890 (judging from the location) graduated from Georgia College was chartered in 1889 as Georgia Normal and Industrial College. Its emphasis at the time was largely vocational, and its major task was to prepare young women for teaching or industrial careers. And we find Minnie in the 1920 US census "teacher, public school" in Stone Mountain, Dekalb, Georgia. (SOURCE: https://familysearch.org/pal:/MM9.1.1/MJDC-S7H with some help from Ancestry.Com.)
