There are a number of issues that come into play with each accusation in the Salem Witch Trials. This is my area of expertise, so I'll try not to be too wordy, but please ask if you want more detail on any area.

1. Likelihood of an accusation depended on the family. The families to focus on in Salem (comprised of Salem Town and Salem Village, the latter petitioning for independence) were the Putnams and the Porters. The Putnams were wealthy and supported making Salem Village an independent community. The Porters were wealthier and depended on Salem Town's control over the Village. In Salem Village, it was impossible to not be tied to this debate. Ann Putnam Jr. accused more people than any other accuser. While she does not target the Porters, she (probably based on her father Thomas' influence) accuses political allies of the Porters like Rebecca Nurse who came from a rich family. The political alliances of your family and how active your family is with that side.

2. You are most likely accused by a daughter (or even mother) of a political opponent's family. However, it isn't necessarily just political factions. The witchcraft accusations allowed vengeance for a lawsuit or feud. Martha Corey was accused early on in the events of 1692, but although she began as a political accusation of the Putnams, some accusers likely had personal motives. The March 12th examination of Corey references "an anceint woman named Goodall" which probably means Goodale. Martha's husband Giles was previously accused and acquitted of murdering a farmhand named Jacob Goodale. The anceint woman is believed to be the mother of Jacob joining this accusation years later.
   The town of Andover saw more accusations than any other town and many of those accusations were based on the Tyler family's feud with the Dane family. You are probably accused by someone tied to political or personal motives against your family even if you are not the perpetrator of a feud.

3. Daily life is significantly impacted for the families of accusers tending to the witchcraft afflictions, but for family not accused life went on by necessity. The gossip certainly discussed the accusations. Ministers encourage reexaminations of your individiual faith since any lapse in faith was cause for Satan to enter the Puritan community. The questioning and trials of suspects were public events and witnesses report that the building holding these proccedings were overflowing with spectators. However, farming and work required constant labor so you couldn't get caught up in the hysteria entirely.

4. Your family may support you or they may also accuse you. John Willard's grandfather-in-law Bray Wilkins was one of his first accusers and a lot of the Wilkins family testified against Willard. William Good said he believed his wife Sarah might be a witch and she was "an enemy to all good." Giles Corey testified against his wife Martha. Other families confessed togehter Ann Foster, her daughter Mary Lacey Sr., and granddaughter Mary Lacey Jr. all confessed an named each other. Same with Samuel Wardwell (who recanted) and his wife Sarah, their daughter Mercy, and Sarah's daughter Sarah Hawkes. Margeret Jacobs confessed and named her grandfather George Jacobs Sr. but later recanted. Not every family confessed together or accused internally. Soon after Rebecca Nurse's accusation, her sisters Mary Easty and Sarah Cloyce began petitioning for Nurse's release with support from the Porter family. Not long after, Easty and Cloyce were both accused. When Mary English was accused, her husband Philip, an excessively wealthy merchant, paid for them to flee, which meant Philip was accused soon too. Elizabeth Cary escaped jail with the help of her husband Nathaniel.
   More often, if you are accused other members of your family had been or soon were named as witches. Some families saw this as a way to remove a disliked in-law, but others confessed together knowing it kept them alive while others actively fought the accustions or escaped.
