In 1728, in the wake of his father’s death, the twelve-year-old heir to five aristocratic titles and the scion of Ireland’s mighty house of Annesley was kidnapped by his uncle and shipped to America as an indentured servant. Only after twelve more years did “Jemmy” Annesley at last escape, returning to Ireland to bring his blood rival, the Earl of Anglesea, to justice in one of the most captivating trials of the century. Hundreds of years later, historian A. Roger Ekirch delves into the court transcripts and rarely seen legal depositions that chronicle Jemmy’s attempt to reclaim his birthright, in the process vividly evoking the volatile world of Georgian Ireland—complete with its violence, debauchery, ancient rituals, and tenacious loyalties.
