Moyra was presented at Court in May 1938. Lord and Lady Ossory hosted a large ball at the London townhouse of the Marquess and Marchioness of Ormonde, 11 Bryanston Square, in June 1938 during Lady Moyra's debutant season. This dance was a joint coming-of-age party for Lady Moyra's brother, Anthony Viscount Thurles, as well as a debutant 'coming-out' party for Moyra. The guest list reported in newspapers at the time provides some insight into the high social standing of the Butler family; among the guests who accepted invitations were the United States Ambassador Joseph Kennedy (father of US President John F. Kennedy) and his daughter Kathleen (later Marchioness of Hartlington), The Earl and Countess of Airlie, Queen Victoria's grandson the Marquess of Carisbrooke, Viscount and Viscountess Curzon, Earl and Countess FitzWilliam, Earl and Countess Spencer, the Duke and Duchess of Marlborough, the Duchess of Northumberland, and the Earl and Countess of Shrewsbury.
