In 1816, due to Leopold's performance on the battlefield, George IV, who was then still the Regent King of Britain, developed a great affection for the young man and decided to marry his daughter, Princess Charlotte, to Leopold.
Leopold thus came to London, and Stockma, as Leopold's private secretary and physician, naturally moved to London with him.
Unfortunately, a year and a half later, Princess Charlotte died in childbirth.
The last person Princess Charlotte saw before her death was neither her husband Leopold nor her father George IV, but Baron Stockma.
It is said that Princess Charlotte, like her husband, greatly admired Baron Stockma and had a high regard for his medical skills.
