Yes, it was a dreadful blow to Mary Adelaide because the woman was always up to her ears in debt. She had the habit of spending up to her income and beyond all her adult life. With the death of Prince Eddy and her daughter's brilliant marriage prospects disappearing the chance of some of those debts being forgiven and a sea of unlimited credit being granted, were gone. Plus, of course, marriage to the heir to the throne was a magnificent social coup and a glittering prize for any Mama, especially one married to a man who was looked down on by many continental royals as being of morganatic stock.
No wonder the Duke of Teck, Mary Adelaide's husband and May's father, went about the house the family took in the South of France following the shock death, saying 'It must be a Tsarevitch, it must be a Tsarevich!' a reference of course to Dagmar of Denmark marrying the future Alexander III of Russia after the premature death of Alexander's elder brother, her fiancé. And so it came to pass.
