In Front of the Alma and LH Rivard Home

The home of LH and Alma Rivard in TL.  During the hard times of the 30’s and into the 40’s, Alma rented two upstairs bedrooms to teachers to supplement the family income.   Annabelle Berg Rivard rented there.  I suspect the top photo is Alma with two teachers. John L Rivard

Who could the tall distinguished woman in the center have been? Was she a teacher? What did she teach?
