============================================

I believe you could not teach and had to resign if you were getting married & or pregnant- so the teacher is a likely match ..Both her & her parents were born in the USA



Etta ia usually short for something - But I am not sure about Mary: http://www.thinkbabynames.com/ending/0/etta/6

Of course Mary could have been her real name & Etta a nickname ?
