Postulates that William Symmes' first wife, mother of his daughter Sarah b. 1652, might have been the "Sarah Simes" who died Cambridge 10 Jun 1653.
[The evidence for this seems weak. First, he assumes the daughter's name Sarah is based on the wife's name, but William's mother was named Sarah, too, so that is not the only likely explanation. Secondly this Sarah Simes wrote a will, which is unlikely for a married woman. Third she mentioned brother John Stedman, and brother William French. A William French married an aunt of Williams' father, and John Stedman married an Alice ---. No relationship is obvious, but both appear to be older than William Symmes based on the births of their children, suggesting this woman was also older, so probably not his wife, but a widow or spinster.]
