pp 19-20: Named in the will of her father. On page 62, McCoy says he infers she was about to be married (probably to the Thomas Ury mentioned in her father's will), and estimates her birth year to be 1729 or 1730 (based on the birth date of her brother Thomas).
p. 45: "Dr. Egles says that he died in March, 1750, which is quite likely correct." McCoy estimates Samuel to have been born about 1706 based on the approx. birth years of his children. (Note that the birth date given here for his son Thomas is based on his age at death; McCoy later gives a different birth date, commenting that his age at death was incorrectly calculated.)
