Birth dates (but not places) are given for Sarah and her siblings. They were taken from a reconstruction "from reliable sources" of Piney Woods Monthly Meeting (Quaker) records destroyed in a fire in 1851. From context, the information was probably provided by a descendant of Sarah's sister Rachel (White) Winslow. Proof that these dates use old-style dating is in the birth date of Mary: 2nd month, 29th day (1735) could not be February, so must be April.
