A working genealogical note in Newton's hand, evidently drawn from a longer document, in which he traces a line of descent through one William Newton, baptized 1541. The verso references questions of heirship and minor children, suggesting the fragment formed part of Newton's private inquiry into the legal and lineal standing of the Newton family. Newton's documented genealogy situates him within the rural gentry of early modern England. He was born at Woolsthorpe Manor, Lincolnshire, to Isaac Newton, a yeoman farmer who died before his son's birth, and Hannah Ayscough, daughter of a local clergyman. The paternal line can be traced to his grandfather Robert Newton, also of Woolsthorpe, indicating a family of modest landholding status. The maternal Ayscough line connected Newton to the educated clerical class, a milieu that may have shaped his early intellectual formation. The present fragment, though brief, offers direct testimony of Newton's own engagement with the question of his ancestry and joins the small body of surviving manuscript material in which he records personal and familial concerns rather than scientific or theological matters.

Condition: In good condition; minor wear consistent with age. The fragment has been archivally encapsulated by PSA/DNA together with a portrait of Newton and the corresponding authentication, with the verso of the autograph remaining visible for examination.

Authentication: PSA/DNA.
