After the marriage, they relocated to neighboring Billerica, some ten miles southwest of Andover, and lived in the north part of town near her sister Mary.

[Note: According to the New England Historic Genealogical Society, Martha's spouse was born Thomas Morgan in Wales.

The Carrier family believes that Thomas was 108 to 109 years old when he died, while walking home with a sack of grain over his shoulder.

Martha was accused of witchcraft in May 1692 by a group of young women known as the Salem Girls who consisted of Susannah Sheldon, Mary Walcott, Elizabeth Hubbard and Ann Putnam Jr, who would travel through Essex County, Massachusetts rooting out suspected witches by engaging in a theatrical display.

The girls accused her of leading a 300 strong witch army, using her occult powers to murder and afflict people with terrible diseases and of being promised the dubious position of "Queen of Hell".

[5] Martha's trial started on 31 May 1692 and she was transported to the Salem Village Meeting House to face the accusing girls, overviewed by judges John Hathorne, Jonathan Corwin, and Bartholomew Gedney.

Samuel Preston blamed the death of one of his cows on Martha claiming that after a disagreement she had placed a hex on the animal.

[7] On June 28, 1692, a summons for witnesses against Martha included Samuel Preston Jr, Phoebe Chandler and John Rogers.

The evidence he found persuasive was the testimony of Martha's 18-year-old son, Richard, and her 7 year-old daughter, Sarah, that she made them become witches to haunt others at her direction.

However, John Proctor wrote governor William Phips that he witnessed these children's torture in the jail where he was also imprisoned.

There is a possibility that she simply did not expect the outcome of the trials would lead to her execution, as she was one of the first Andover citizens accused and clearly believed the proceedings were a ridiculous invention of a group of adolescents.

Others, seeing the punishment meted, quickly confessed to outrageously trumped up charges, often naming Martha as a principal ringleader in return for clemency.

Cheering crowds lined the streets and gathered at the scaffold to witness the hanging of Martha and the four men who were also convicted of witchcraft.
