'NICHOLS. p. 876. Mrs. Mary wife of Cyprian. Hartford, 1668/9'
While other interpretations of the data are possible (such as that Mary was the wife of a different Cyprian Nichols, possibly an earlier generation, or that Mary was this Cyprian's wife but not the mother of his children), the simplest explanation is that this Mary was the wife of this Cyprian and the mother of his children. In the absence of other evidence, this assumption is made.
