Newton was born three months after the death of his father, a prosperous farmer also named Isaac Newton. His father was described as a "wild and extravagant man". Born prematurely, young Isaac was a small child; his mother Hannah Ayscough reportedly said that he could have fitted inside a quart mug. When Newton was three, his mother remarried and went to live with her new husband, the Reverend Barnabus Smith, leaving her son in the care of his maternal grandmother, Margery Ayscough. The young Isaac disliked his stepfather and held some enmity towards his mother for marrying him, as revealed by this entry in a list of sins committed up to the age of 19: "Threatening my father and mother to burn them and the house over them." Later on his mother returned after her husband died.
