George Blanchard had two wives according to Wyman: _____ Hills (perhaps Elizabeth), and Mary _____. Wyman does not identify which was the mother of daughter Elizabeth; several websites make her mother Elizabeth Hills, in which case her pedigree can be traced further. Her mother, Rose, may have been Rose Dunster, sister to Henry Dunster, the first President of Harvard, but she may also have been a Rose Clarke.

There is some question as to whether this George Blanchard was the father of Elizabeth (as Wyman reports), or whether her father was a John Blanchard. This requires further investigation.
