Maria Olsdotter

Maria Olsdotter (1763–1856), was a Swedish miner. She owned and managed the iron ore mine of Stråssa in Bergslagen. She actively participated in the mining herself and has been referred to as the first woman mining inspector in Sweden. She became a famous figure in local folk lore, and are known as "Gruvmora i Stråssa" ('Miner Mother of Stråssa') and "Gruv-Mor" ('Miner Mum').
Life.
She was the fourth of five daughters of the miner ”Mosis-Olle” Olof Ohlsson and Anna Israelsdotter. She and her siblings worked with their parents in the mine as children. In 1783, she married Erik Larsson (d. 1817), with whom she had one child, the daughter Anna-Stina Ersdotter (d. 1876). Her husband was the son of the owner of the Stråssa mine. The marriage was reportedly very happy. After the death of her husband in 1817, she took over the management of the Stråssa mine: brought up as a miner, she did not merely own the mine but personally lead the work as overseer and inspector, and was as such a pioneer as the likely first woman in Sweden to have done so. 
Maria Olsdotter was became known in her own time as well as in history for the many stories which were told about her. She was known as a bold hunter, accompanied her husband during the hunt and then hunted alone with all-male hunting companions, and was known for her achievements as a hunter. Apparently, she enjoyed to use spells to enhance her success and affect the weather: this was a common practice in traditional folk belief, but whether she believed them or simply used them as a habit is unknown. Nevertheless, they were a part of her eccentricity, though she laughed about them when the stories were commented to her. 
She was the maternal aunt of the famous con artist Lasse-Maja, who described his aunt:
Lasse-Maja later blamed his aunt and her daughter Anna-Stina Ersdotter for having enticed him to his criminal activity, and it is clear that they played an important role in his life.
