This book is an extraordinary genealogical exploration that transcends borders and centuries, tracing the author's lineage from modern-day Sydney back to the noble courts and ancient strongholds of Europe. Driven by a passion for uncovering family history, Dr Rockwell embarks on a remarkable journey through time, revealing ancestral ties to the illustrious O'Sullivan, Mahony, and MacCarthy clans of Ireland, and extending to the royal dynasties of France, England, Scotland, and beyond. This meticulously researched work uncovers connections to historical giants such as Charlemagne, William the Conqueror, and the Plantagenet kings of England, weaving a rich tapestry of aristocratic alliances, dynastic marriages, and storied legacies. So expansive and illuminating has been the research that results have enabled the publication of three volumes, the final volume of which, examines in two sections the descent of the royal and noble gaelic ancestors of the FitzGerald and Butler dynasties, as well as our most recent descendants. More than a mere pedigree, this reference book breathes life into the triumphs, trials, and enduring in uence of Dr Rockwell's ancestors, offering readers a fascinating glimpse into how centuries of royal and noble heritage converge in one Australian lineage.
