Mont Saint-Michel (Alsace): Mont Saint-Michel (German: "Michaelsberg" ) is a hill, 437 metres high, in the Vosges mountains in the French region of Alsace.  It rises above the town and abbey of Saint-Jean-Saverne ("St. Johann bei Zabern").

Huayangosaurus: Huayangosaurus is a genus of stegosaurian dinosaur from the Middle Jurassic of China.  The name derives from "Huayang" (華陽), an alternate name for Sichuan (the province where it was discovered), and "saurus", meaning "lizard".  It lived during the Bathonian to Callovian stages, around 165 million years ago, some 20 million years before its famous relative, "Stegosaurus" appeared in North America.  At only 4.5 metres long, it was also much smaller than its famous cousin.  Found in the Lower Shaximiao Formation, "Huayangosaurus" shared the local Middle Jurassic landscape with the sauropods "Shunosaurus", "Datousaurus", "Omeisaurus" and "Protognathosaurus", the ornithopod "Xiaosaurus" and the carnivorous "Gasosaurus".  It was found in Huayang in China.

His debut was in 1940 with a collection of poems, "Syngende Jord" (Singing Earth).

He was known as a master translator, and translated works by Shakespeare, Molière, Goethe, Racine, etc. into elegant Norwegian.  A central theme in Bjerke's works, especially his poems, is the longing for childhood.  André Bjerke was, together with his equally famous cousin Jens Bjørneboe, also known as a prominent proponent of the Riksmål language during the Norwegian language struggle, and of anthroposophy, especially in the 1950s.

He was born in Hove and died in Cheltenham.  He appeared in twenty first-class matches as a righthanded batsman who bowled right arm medium pace with a roundarm action.  He scored 169 runs with a highest score of 33 and took 31 wickets with a best performance of three for 11.  He is termed "senior" in sources to differentiate between him and his more famous cousin James Lillywhite junior.  He was a member of the Lillywhite family which was famous in 19th century cricket and devised the annual season review named after him: James Lillywhite's Cricketers' Annual.

Lady Jane Seymour: Lady Jane Seymour (c.1541 – 19 March 1561) was an influential writer during the sixteenth century in England, along with her sisters, Lady Margaret Seymour and Anne Seymour, Countess of Warwick.  Their brother was Edward Seymour, 1st Earl of Hertford.  They were the children of Edward Seymour, 1st Duke of Somerset, who from 1547 was the Lord Protector of England after the death of King Henry VIII and during the minority of Jane's first cousin, King Edward VI.  She was baptised 22 February 1541, and her godparents were Thomas Cromwell (the King's chief minister), Lady Mary (the King's daughter, at the time declared illegitimate but later to become queen) and Katherine Howard, the fifth wife of Henry VIII, and queen at the time.  Jane was thus the niece of Henry VIII's third wife, Queen Jane, whom she was probably named after.  She was the sole witness to the secret marriage of her brother Edward to Lady Catherine Grey (a potential heir to Queen Elizabeth I) in 1560.  She died a year later, aged 20, probably of tuberculosis.

Barbara Radziwiłł: Barbara Radziwiłł (Polish: "Barbara Radziwiłłówna" , Lithuanian: "Barbora Radvilaitė" ; 6 December 1520/23 – 8 May 1551) was Queen of Poland and Grand Duchess of Lithuania as consort of Sigismund II Augustus, the last male monarch of the Jagiellon dynasty.  Barbara, a great beauty and already widowed, became a royal mistress most likely in 1543 and they married in secret in July or August 1547.  The marriage caused a scandal; it was vehemently opposed by Polish nobles, including Queen mother Bona Sforza.  Sigismund Augustus, assisted by Barbara's cousin Mikołaj "the Black" Radziwiłł and brother Mikołaj "the Red" Radziwiłł, worked tirelessly to gain recognition of their marriage and to crown Barbara as Queen of Poland.  They succeeded and Barbara's coronation was held on 7 December 1550 at Wawel Cathedral.  However, her health was already failing and she died just five months later.  Even though it was brief, her reign propelled the Radziwiłł family to new heights of political power and influence.

Florence Baker: Florence, Lady Baker or Barbara Szász; Maria Freiin von Sass; Barbara Szasz; Barbara Maria Szász; Barbara Maria Szasz (Hungarian: "Sass Flóra" ; 6 August 1841 – 11 March 1916) was a Hungarian–British explorer.  Born in Transylvania (then Austrian Empire), she became an orphan and was sold as a slave to Samuel Baker.  Together they went in search of the source of the River Nile and found Lake Albert.  They journeyed to Samuel Baker's home in England where they were married and she became Lady Baker.  She later returned to Africa with her husband to try and put down the slave trade.  They both retired and died in Devon.

Lady Xun: Lady Xun (personal name unknown) (; died 335), formally Lady of Yuzhang (豫章君), was a concubine of Emperor Yuan of Jin (Sima Rui) while he was the Prince of Langye.  Initially, he favored her greatly, and she bore him two sons -- Sima Shao (Emperor Ming) and Sima Pou (司馬裒).  Because of the favor that she received, Sima Rui's wife Princess Yu Mengmu (虞孟母) was very jealous of her and mistreated her.  Lady Xun, not happy about her low station and Princess Yu's mistreatment, often complained and was rebuked by Prince Rui.  Eventually, he threw her out of the household.  After Sima Shao succeeded to the throne as Emperor Ming in 323, he gave her a mansion and created her the Lady of Jian'an.  Later that year, he welcomed her back to the palace.  After he died and his son Emperor Cheng succeeded to the throne, she was treated as virtual empress dowager without the title, and she probably effectively raised Emperor Cheng, since Emperor Cheng's mother Empress Yu Wenjun died in 328 in the midst of the Su Jun Disturbance, while Emperor Cheng was only seven.  She died in 335 and was posthumously created the Lady of Yuzhang, and a temple was built for her.  Some sources mentions that she was a Xianbei.
