More compelling than any novel, All Worlds Possible is an entrancing story. It reaches back to tap the life and times of a farming family in nineteenth century Ireland and it reaches out to embrace the spread of family, friends and relations over far-flung corners of the earth. From start to finish everything crystallises around the Millers of Coolybrown, a Palatine family from near Reens in west Co. Limerick, and from fragmentary sources, Patrick J. O'Connor, winner of the Irish historical research prize in 1987 and 1989, has forged a masterly synthesis. All Worlds Possible is a touching evocation of the Millers in their many and varied settings, extending from the 1820s to the 1960s.
