Nils and Margaret Mattson arrived in New Sweden on May 22, 1654, on the ship Orn Margaret Mattson and her husband Nils Mattson lived on a farm near Ridley Creek in present-day Eddystone, Pennsylvania. Part of Eddystone township at the mouth of Ridley Creek, had been taken up by Olof Persson Stille, one of the early settlers of the Swedish colony of New Sweden who had arrived during 1641. One hundred acres of the Stille land was patented to Neals Mattson on June 13, 1670. Mattson's choice for their plantation was rich, fertile river land by the Delaware River. Of Swedish-Finnish descent, Neals and Margaret Mattson were also likely members of the former New Sweden colony which occupied much of the lower Delaware River Valley from 1638 to 1655. Mattson was a reputed healer working from Finnish tradition. New Sweden was taken over first in 1654 by the Dutch, then in 1664 by the British. In 1683, some of her neighbors claimed that she had bewitched cattle. Charges of practicing witchcraft were brought before the Pennsylvania Provincial Council on February 7, 1683. This occurred one and a half years after William Penn arrived on October 27, 1682, on the vessel Welcome and landed to take seisin possession of Pennsylvania, his royal land grant colony of "Penn's Woods" named after his father by King Charles II. Pennsylvania was a common law colony and the law of England applied. The English Witchcraft Act of 1604 made conjuration, witchcraft, and dealing with evil and wicked spirits a felony offense punishable by death by hanging without benefit of clergy. Like other British colonies, Pennsylvania was subject to the James I of England 1604 statute against witchcraft; however, Mattson's and Hendrickson's is the only such trial recorded from the Pennsylvania Colony. Accused by several neighbors, as well as her own daughter in law, Mattson's alleged crimes included making threats against neighbors, causing cows to give little milk, bewitching and killing livestock and appearing to witnesses in spectral form. On February 27, 1683, charges against Mattson and a neighbor Gertro Hendrickson were brought by the Attorney General before a grand jury of 21 men overseen by the colony's proprietor, William Penn. The grand jury returned a true billindictment that afternoon, and the cases proceeded to trial. A petit jury of 12 men was selected by Penn and an interpreter was appointed for the Finnish women, who did not speak English. Penn barred the use of prosecution and defense lawyers, conducted the questioning himself, and permitted the introduction of unsubstantiated hearsay. Penn himself gave the closing charge and directions to the jury, but what he told them was not transcribed. According to the minutes of the Provincial Council, dated February 27, 1683, the jury returned with a verdict of "Guilty of having the Comon Fame of a Witch, but not Guilty in manner and Forme as Shee stands Endicted." Thus Mattson was found guilty of having the reputation of a witch, but not guilty of bewitching animals. Neither woman was convicted of witchcraft. "Hence the superstitious got enough to have their thinking affirmed. Those less superstitious, and justice minded, got what they wanted." The accused were released on their husbands posting recognizance bonds of 50 pounds and promising six months' good behavior. A popular legend tells of William Penn dismissing the charges against Mattson by affirming her legal right to fly on a broomstick, saying "Well, I know of no law against it." The record fails to show any such commentary, but the story probably reflects popular views of Penn's socially progressive Quaker values.
