My great grand aunt was a schoolteacher - one of her first schools was in a coal mining town that had run out several teachers before her term - she had 70 pupils of all ages. In 1890 she married before her local school term was finished, so each lived with their own parents. When she made out the final report cards, she signed them "Mrs. Frank McCalister". In that era, if a woman married, she wouldn't/couldn't be a teacher any longer.
