William Penn signed this birth certificate as a witness during his final two-year sojourn in Pennsylvania. This document is signed by a midwife and five other women, including Penn’s second wife Hannah, who were present at the birth of Isaac Penington on November 22, 1700. In addition, William Penn, his daughter Latitia (1678-1746), and three others also signed the document because they were present at the naming of the child on December 13, 1700. The baby was the only child of Penn’s first wife’s half-brother Edward Penington, making William Penn the baby’s uncle by marriage.
