How great her power over her sisters was may be judged from what they declared in after years in prison, and from what they endured for her sake. Barbara, the eldest, professed to the prison chaplain in Zürich, in 1823, "I am satisfied that God worked in mighty power, and in grace through Margaret, up to the hour of her death." The father himself declared after the ruin of his family and the death of two of his daughters, "I am assured that my youngest daughter was set apart by God for some extraordinary purpose." When Margaret was six, she was able to read her Bible, and would summon the family about her to listen to her lectures out of the sacred volume. She would also at the same time pray with great ardour, and exhort her father and sisters to lead God-fearing lives. When she read the narrative of the Passion, she was unable to refrain from tears; her emotion communicated itself to all assembled round her, and the whole family sobbed and prayed aloud. She was a veritable "ministering child" to her household in all things spiritual. As she had been born at Christmas, it was thought that this very fact indicated some special privilege and grace accorded to her. In 1811, when aged seventeen, she received her first communion and edified all the church with the unction and exaltation of soul with which she presented herself at the table. In after years the pastor of Trüllikon said of her, "Unquestionably Margaretta was the cleverest of the family. She often came to thank me for the instructions I had given her in spiritual things. Her promises to observe all I had taught her were most fervent. I had the best hopes for her, although I observed somewhat of extravagance in her. Margaretta speedily obtained an absolute supremacy in her father's house. All must do what she ordered. Her will expressed by word of mouth, or by letter when absent, was obeyed as the will of God." In personal appearance Margaretta was engaging. She was finely moulded, had a well-proportioned body, a long neck on which her head was held very upright; large, grey-blue eyes, fair hair, a lofty, well-arched brow. The nose was well-shaped, but the chin and mouth were somewhat coarse. In 1816, her mother's brother, a small farmer at Rudolfingen, invited her to come and manage his house for him. She went, and was of the utmost assistance. Everything prospered under her hand. Her uncle thought that she had brought the blessing of the Almighty on both his house and his land.
