↑ The age at death place her birth too early as her parents didn't marry until 22 Jan 1712-13. The first child, James, is born a year later, and Peter is born 2 years after that, before there is a 4 year gap where her birth probably occurred. This would be about 1718. Her age at death was probably closer to 30, than 40.
