Sir Isaac Newton was born (according to the Julian calendar, in use in England at the time) on Christmas Day, 25 December 1642 (N.S. 4 January 1643) "an hour or two after midnight", at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire, England. His father, also named Isaac Newton, died three months before his birth. When Newton was three, his mother, Hannah Ayscough, remarried with Reverend Barnabas Smith. Young Newton remained with his maternal grandmother, Margery Ayscough.
