Prince George of Denmark
Prince George of Denmark and Norway, Duke of Cumberland (2 April 165328 October 1708), was the husband of Queen Anne, who reigned over Great Britain from 1702 to 1714.
His marriage to Anne was arranged in the early 1680s with a view to developing an Anglo-Danish alliance to contain Dutch maritime power.
As a result, George was unpopular with his Dutch brother-in-law, William III of Orange, who was married to Anne's elder sister, Mary.
William and Mary became joint monarchs of Britain, with Anne as their heir presumptive, in 1689 after the "Glorious Revolution" deposed James II and VII, the father of both Anne and Mary.
William excluded George from active military service, and neither George nor Anne wielded any great influence until after the deaths of Mary and then William, at which point Anne became queen.
During his wife's reign, George occasionally used his influence in support of his wife, even when privately disagreeing with her views.
He had an easy-going manner and little interest in politics; his appointment as Lord High Admiral in 1702 was largely honorary.
Anne's seventeen pregnancies by George resulted in twelve miscarriages or stillbirths, four infant deaths, and a chronically sick son, William, who died at the age of eleven.
Despite the history of their children, George and Anne's marriage was a strong one.
George died aged 55 from a recurring and chronic lung disease, much to the devastation of his wife, and he was buried in Westminster Abbey.

Prince William, Duke of Gloucester
Prince William, Duke of Gloucester (24 July 1689 – 30 July 1700), was the son of Princess Anne (later Queen of England, Ireland and Scotland from 1702) and her husband, Prince George of Denmark.
He was their only child to survive infancy.
Styled Duke of Gloucester, he was viewed by contemporaries as a Protestant champion because his birth seemed to cement the Protestant succession established in the "Glorious Revolution" that had deposed his Catholic grandfather James II the previous year.
Anne was estranged from her brother-in-law and cousin, William III, and her sister, Mary II, but supported links between them and her son.
He grew close to his uncle William, who created him a Knight of the Garter, and his aunt Mary, who frequently sent him presents.
At his nursery in Campden House, Kensington, he befriended his Welsh body-servant, Jenkin Lewis, whose memoir of the Duke is an important source for historians, and operated his own miniature army, called the "Horse Guards", which eventually comprised 90 boys.
Gloucester's precarious health was a constant source of worry to his mother.
His death in 1700 at the age of 11 precipitated a succession crisis as his mother was the only individual remaining in the Protestant line of succession established by the Bill of Rights 1689.
The English Parliament did not want the throne to revert to a Catholic, and so passed the Act of Settlement 1701, which settled the throne of England on Electress Sophia of Hanover, a cousin of King James II, and her Protestant heirs.
