Title: Children of Henry VIII
Content:  Henry VIII of England had several children. The best known children are the three legitimate offspring who survived infancy and would succeed him as monarchs of England successively, Edward VI, Mary I and Elizabeth I. His first two wives, Catherine of Aragon and Anne Boleyn, had several pregnancies that ended in stillbirth, miscarriage, or death in infancy. Henry acknowledged one illegitimate child, Henry FitzRoy, as his own, but is suspected to have fathered several illegitimate children by different mistresses. The number and identity of these is a matter of historical debate. There are many theories about whether Henry VIII had fertility difficulties. His last three wives, Anne of Cleves, Catherine Howard and Catherine Parr are not known to have conceived by him, although Parr conceived in her next marriage. None of Henry's acknowledged children (legitimate or otherwise) had children of their own, leaving him with no direct descendants after the death of Elizabeth in 1603.
Title: Wives of Henry VIII
Content:  Boleyn, and Jane Seymour each gave him one child who survived infancy: two daughters and one son. All three of these children eventually ascended to the throne as King Edward VI, Queen Mary I, and Queen Elizabeth I. Catherine Howard and Anne Boleyn were first cousins and were both beheaded. Jane Seymour was second cousin to both Anne Boleyn and Catherine Howard. Several of Henry's wives worked in service to another wife, typically as a lady-in-waiting: Anne Boleyn served Catherine of Aragon, Jane Seymour served both Catherine of Aragon and Anne Boleyn, and Catherine Howard served Anne of Cleves.
Title: English and British royal mistress
Content:  Henry VIII's three children followed him of the throne, but none of them appears to have had a lover. His son Edward VI died before he was sixteen, and was followed by his two sisters Mary I of England and Elizabeth I of England. Elizabeth I's status as a 'Virgin Queen' was an important part of her public image. Although she clearly had favourites, there is no clear evidence that any of these was a lover.
Title: Henry IV of England
Content:  Henry had four sons from his first marriage, which was undoubtedly a clinching factor in his acceptability for the throne. By contrast, Richard II had no children and Richard's heir-presumptive Edmund Mortimer was only seven years old. The only two of Henry's six children who produced legitimate children to survive to adulthood were Henry V and Blanche, whose son, Rupert, was the heir to the Electorate of the Palatinate until his death at 20. All three of his other sons produced illegitimate children. Henry IV's male Lancaster line ended in 1471 during the War of the Roses, between the Lancastrians and the Yorkists, with the deaths of his grandson Henry VI and Henry VI's son Edward, Prince of Wales.
Title: Henry II of England
Content:  older sons in the Great Revolt of 1173–74. Probable explanations include Henry's persistent interference in Aquitaine, his recognition of Raymond of Toulouse in 1173, or his harsh temper. He had several long-term mistresses, including Annabel de Balliol and Rosamund Clifford. Henry had eight legitimate children by Eleanor, five sons—William, the Young Henry, Richard, Geoffrey and John, and three daughters, Matilda, Eleanor and Joan. He also had several illegitimate children; amongst the most prominent of these were Geoffrey (later Archbishop of York) and William (later Earl of Salisbury). Henry was expected to provide for the future of his legitimate children, either through granting 
Title: Henry XI of Legnica
Content:  (1535 – 1587), daughter of George, Margrave of Brandenburg-Ansbach. Their relationship was contentious. Both had strong personalities and the public quarrels between them were mostly because of Henry XI's affairs with other women. They had six children:  Of his two sons, the elder was either stillborn or died shortly after birth, and the second lived only three months; of his four daughters, the youngest lived 23 months. His eldest daughter, Katharina Sophie, by marriage Countess Palatine of Zweibrücken-Vohenstrauss-Parkstein, gave birth to a daughter and twin sons, but all died before five months of age. Without proper dowries, his other two daughters Anna Maria and Emilia remained unmarried.
Title: Henry VIII
Content:  Upon Henry's death, he was succeeded by his son Edward VI. Since Edward was then only nine years old, he could not rule directly. Instead, Henry's will designated 16 executors to serve on a council of regency until Edward reached 18. The executors chose Edward Seymour, 1st Earl of Hertford, Jane Seymour's elder brother, to be Lord Protector of the Realm. If Edward died childless, the throne was to pass to Mary, Henry VIII's daughter by Catherine of Aragon, and her heirs. If Mary's issue failed, the crown was to go to Elizabeth, Henry's daughter by Anne Boleyn, and her heirs. Finally, if Elizabeth's line became extinct, the crown was to be inherited by the descendants of Henry VIII's deceased younger sister, Mary, the Greys. The descendants of Henry's sister Margaret—the Stuarts, rulers of Scotland—were thereby excluded from the succession. This provision ultimately failed when James VI of Scotland became King of England in 1603.
Title: Henry VII of England
Content: Arthur (19 September 1486 – 2 April 1502), Prince of Wales, heir apparent from birth to death ; Margaret (28 November 1489 – 18 October 1541), Queen of Scotland as the wife of James IV and regent for their son James V ; Henry VIII (28 June 1491 – 28 January 1547), Henry VII's successor ; Elizabeth (2 July 1492 – 14 September 1495) ; Mary (18 March 1496 – 25 June 1533), Queen of France as the wife of Louis XII ; Edmund (21 February 1499 – 19 June 1500), styled Duke of Somerset but never formally created a peer ; Katherine (2 February 1503 – 10 February 1503) Henry VII and Elizabeth had seven children: Sir Roland de Velville (or Veleville) was knighted in 1497 and was Constable of Beaumaris Castle. He is sometimes presented as the clear "illegitimate issue" of Henry VII of England by "a Breton lady whose name is not known". The possibility this was Henry's illegitimate son is baseless.
Title: Henry III of England
Content:  by celebrations and donations to the poor. The third child, Beatrice, was named after Eleanor's mother, and born in 1242 during a campaign in Poitou. Their fourth child, Edmund, arrived in 1245 and was named after the 9th-century saint. Concerned about Eleanor's health, Henry donated large amounts of money to the Church throughout the pregnancy. A third daughter, Katherine, was born in 1253 but soon fell ill, possibly the result of a degenerative disorder such as Rett syndrome, and was unable to speak. She died in 1257 and Henry was distraught. His children spent most of their childhood at Windsor Castle and he appears to have been extremely attached to them, rarely
