This is the last known photograph of Huguette, cornered by a photographer on the day of her divorce in August 1930. In 1931, an Irish nobleman denied reports that he would marry Huguette, then 24. She dropped her seat at the opera, and slipped from the society pages.
There were newspaper accounts in 1931, apparently false, that Huguette was ready to wed an Irish nobleman named Edward FitzGerald, the Seventh Duke of Leinster. The duke, a compulsive gambler and ne'er-do-well, later admitted in court that he was bankrupt when he came to America "with the idea of marrying someone rich." He died by suicide, penniless.
