We can also add princess Leila Pahlavi, daughter of the last Shah of Iran, who died at age of 31.

But then the longlivity ist only since the descendants of Oscar II. Oscar I. for example did not become very old and also Carl XV.Many, if not the majority, of members in the Swedish royal Bernadotte have lived long lives, into their 80s and even 90s, but here are a few who have died young.
Prince Gustaf, son of Oscar I, 1827 - 1853, 25 years old
Carl Oscar, son of Carl XV, December 1852 - March 1854, 1 year old
Erik, son of Gustaf V, 1889 - 1918, 29 years old
Well, Karl XVI Johan was 81 years old when he died, his wife, Desiree, lived to be 83. Oscar I had had a weak health, and died of a brain tumor. Four of his children died between the ages of 25 and 58, by tuberculosis (Carl), typhoid fever (Gustaf), and lung problems (August and Eugenie). It's very possible that Oscar I, as well as his four children had been infected by tuberculosis, I remember reading once that one of the royal childrens' teacher had had tuberculosis. Today most likely all of them would have benefited from antibiotics, and surgery. Oscar II lived to be 78, but had health problems during the last years of his life.But then the longlivity ist only since the descendants of Oscar II. Oscar I. for example did not become very old and also Carl XV.

This is where we say that it is the will of god, that the family tree split a bit.It's interesting that two early deaths in the last 208 years have lead to the present British Royal Family as it is today. The death of Princess Charlotte of Wales (and her stillborn son), the daughter of the future George IV, at the age of 21 in 1817, and Prince Albert Victor, the son of the future Edward VII, at the age of 28 in 1892. If any of them would had have surviving issue, then the members of British Royal Family would have been others than those today. Maybe also the Belgian Royal Family and Luxembourg Grand ducal Family would have been different from todays.
Or if one of the 2 daughters of the future King William IV. had survived and succeeded her father ...It's interesting that two early deaths in the last 208 years have lead to the present British Royal Family as it is today.
