Rarely (but thrillingly) a book comes along that makes everything else ever written on the same subject instantly redundant.
There must have been more books written about Guinness, the brand and its brewers, than any other in the world. I’ve got 14, now, four of them written by people called Guinness. But the latest to be published, Arthur’s Round, by Patrick Guinness, is the first to concentrate on the patriarch himself, the founder of the concern at St James’s Gate in Dublin, and it uses everything from proper, evidence-based historical research to genetic analysis to debunk more myths about Arthur Guinness and the early years of his brewing concern than you could shake a shillelagh at.
The biggest myth Patrick Guinness destroys, using modern genetic techniques, is the claim that Arthur Guinness and his father Richard were descended from the Magennis chieftains of Iveagh, in County Down, Ulster, in Irish Mac Aonghusa. The last-but-one Viscount Iveagh, Bryan Magennis had fled abroad after James II’s defeat at the Battle of the Boyne in 1690, about the time Arthur Guinness’s father was born, and the Magennis lands in Ulster were confiscated in 1693.
