Born 1669. Could not have been having children 1729 - 1740 as is currently the way her family group is set up, as she would have been 59 - 70 years old.
Information in her mother's profile Mary Cudworth indicates that Sarah died about 1699, unmarried.
Could the Sarah who had these children actually belong to the next generation? And perhaps be the daughter of one of the siblings of Sarah (born 1669)?
According to My Heritage Nathaniel was married to Zerviah Cudworth
