FitzGerald and West own a town house in Shepherd's Bush, London, a home in the Cotswolds, and share ownership of Glin Castle with her sister.
2011
In 2011, FitzGerald’s father died.
As her father had no male heirs, the hereditary knighthood of Glin became extinct.
FitzGerald, along with her mother and sisters, decided to sell the estate through an auction at Christie’s.
The castle, which had operated in the hospitality trade, did not sell, so FitzGerald and West, along with FitzGerald's sisters, bought it to keep it in the family.
They split their time between Glin Castle and their home in London.
FitzGerald and West first operated the castle as a bed and breakfast and now run it as a hotel and event venue.
