The Prince Octavius (23 February 1779 – 3 May 1783) was a member of the British Royal Family as the thirteenth child and eighth son of King George III and his queen consort Charlotte of Mecklenburg-Strelitz. Six months after the death of his brother Prince Alfred, Octavius was inoculated from the smallpox virus. Several days later, he became ill. His subsequent death at the age of four devastated his parents, and in particular his father. George bemoaned his son`s death, of whom he was exceedingly fond; the king`s later bouts of madness would involve hallucinations of his young son.
