For Greg Withers & Anna Maria Bligh
"Her mother Frances Tancred, her husband Greg Withers and her two sons, Joseph and Oliver, afforded the kind of support men in politics take for granted and even today only a few women can rely on."
Independent of the official biography, and useful twice over: it names the elder son 'Joseph' where the official biography abbreviates to 'Joe', and it names her mother as Frances Tancred, matching tree person #50068 Frances Mary Tancred - which fixes the identification of this family beyond doubt.
