Question: Francis Manners, 6th Earl of Rutland, (1578–1632) was an English nobleman, in what year, did three women, the "Witches of Belvoir", were accused of witchcraft, for having allegedly caused the deaths of his two young sons?

full_context: Document 1: Witches of Belvoir: The Belvoir Witches were three women, a mother and her two daughters, accused of witchcraft in England around 1618. The mother, Joan Flower, died on the way to her trial, and the two daughters, Margaret and Philippa, were supposed to be hung in Lincoln. It is said that Phillipa drugged the guards and managed to escape and making her way to Kent where she died after having 3 children.
Document 2: Mary Webster (alleged witch): Mary Webster, née Reeve, was a resident of Puritan Hadley, Massachusetts, who was accused of witchcraft. She was born in England. Her exact birth year is unknown but is believed to be around 1624. Accounts of her birthdate range from 1617 to 1624. Both her father and her brother were named Thomas Reeves. Her father lived in Springfield, Massachusetts. Her mother's name is not known.
Document 3: Black Widows of Liverpool: Catherine Flannagan (1829 – 3 March 1884) and Margaret Higgins (1843 – 3 March 1884) were Irish sisters who were convicted of poisoning and murdering one person in Liverpool, Lancashire, England and suspected of more deaths. The women collected a burial society payout, a type of life insurance, on each death, and it was eventually found that they had been committing murders using arsenic to obtain the insurance money. Though Catherine Flannagan evaded police for a time, both sisters were eventually caught and convicted of one of the murders; they were both hanged on the same day at Kirkdale Prison. Modern investigation of the crime has raised the possibility that Flannagan and Higgins were known or believed by investigators to be only part of a larger conspiracy of murder-for-profit—a network of "black widows"—but no convictions were ever obtained for any of the alleged conspiracy members other than the two sisters.

Document 15: Tobacco brides: In 1619, 90 young single women from England went to Jamestown to become wives of the men there, with the women being auctioned off for 150 pounds of tobacco each (to be paid to the shipping company), as that was the cost of each woman's travel to America. All 90 of them did indeed become wives. The youngest, Jane Dier, had been fifteen or sixteen years old when she left, and one of the oldest, Alice Burges, was twenty-eight. Most of their fathers had died. Such voyagers were called tobacco brides (or King's daughters, Casket girls, or Jamestown brides) and 150 pounds of tobacco was the typical auction price for them, although they usually had the right to refuse the highest bidder. However, tobacco brides were often sent to America against their will, and often sent at very young ages. There were many women and girls who went to America for this purpose (the 1619 voyage being the first), with the women and girls promised free passage and trousseaus for their trouble. Many tobacco brides came to America fleeing hardship, but many also suffered once in America. 144 tobacco brides were brought to Jamestown by the Virginia Company between 1619 and 1622, but only six of them lived through their first six years in America.
