Yi Bangja, Crown Princess Uimin of Korea (also "Euimin", Japanese: 李方子 "Ri Masako") (4 November 1901 – 30 April 1989) was the consort of Crown Prince Euimin of Korea. She and her husband would have been the emperor and empress of the Empire of Korea if Korea had not been annexed to the Empire of Japan in 1910.
Yi Bangja and Crown Prince Euimin were born in 1901.
The statement meets the requirements of the category because the excerpt states that Yi Bangja was born in 1901, but does not give an exact birth date for Euimin. I think it was difficult for the system because an exact date is given for one of the two.
