Patrick Desmond Carl Alexander Guinness, KCEG KLJ (born 1 August 1956 in Dublin) is an Irish historian and author and one of heirs of the Guinness business dynasty. Son of Desmond Guinness and Marie-Gabrielle von Urach, he was educated at Winchester College and Trinity College Dublin. He continues his father's business in real estate development and is a financial analyst. He formerly represented Sotheby's in Ireland.


A historian, Patrick Guinness has authored the first biography of Arthur Guinness, the founder of the Guinness Brewery dynasty.[1][2] He has lectured on genetic genealogy relating to the early Irish dynasties and Viking Ireland, and has sponsored academic research on Irish genetics.[3][4] He was a council member of the County Kildare Archaeological Society (2004–2014)[5] and of the Order of Clans of Ireland.

He has produced monographs on the early history of the Friendly Brothers of St Patrick in Kildare, 1758–91;[6] on the depositions from Kildare on the outbreak of the Irish Rebellion of 1641;[7] and on the Irish Jacobite ancestry of the Mitford family (privately published).


His daughter, by his first marriage to Liz Casey, is model Jasmine Guinness. He remarried in 1990 to Louise Arundel; the couple has four children: Celeste, Tom, Lily and George.

Through his maternal great-grandfather, the 2nd Duke of Urach, he is a potential claimant to the medieval Kingdom of Jerusalem, the Kingdom of Lithuania and to the Principality of Monaco (see Monaco Succession Crisis of 1918). He is also 2259th in line of succession to the British throne. In 2015 he gave a lecture on Irish history at the Princess Grace Irish Library in Monaco.[8]

Partly because of previous family involvements, he is a trustee of the Iveagh Trust social housing provider, and is a former president of the Irish Georgian Society.[9]


In September 2010, he became a Knight of Justice of the Military and Hospitaller Order of St. Lazarus of Jerusalem at a ceremony in St. Patrick's Cathedral in Dublin. In 2013, he was made a Knight Commander of the Order of the Eagle of Georgia by Prince David Bagrationi Mukhran Batonishvili, head of the Royal House of Georgia.[10]

On 10 March 2015 the Texas Senate passed a resolution sponsored by Senator Kirk Watson welcoming Guinness to the Texas State Capitol.[11]
