It seems likely that there aren't very many individuals in history who can claim both a king of England and Jamaican slaves as 5x-great grandparents. Sir Hubert Jerningham (1842-1914), a diplomat who served as Governor of Trinidad and Tobago from 1897-1900, is one who could.

Through his paternal grandfather, the barrister Edward Jerningham, Sir Hubert was a descendant of Charles II, King of England. His paternal grandmother, Emily Middleton, has no known royals in her ancestry, but that ancestry is just as fascinating, if not more so.
John Augier was an Englishman who immigrated to Jamaica, and became a planter there, in the late 17th-century, if not during the actual reign of Charles II, then no doubt not long after it. He was a typical British colonial planter of that time: he owned slaves, and took one as a mistress. What was atypical of Augier was that "He seems to have had little connection to his origins and a fondness and care for his Jamaican family". He died in 1722, by his will freeing his five mulatto daughters, and granting them each a share of his estate:

"Like other persons of colour manumitted by will or deed, the Augiers received a limited sort of freedom; irrespective of sex, freed slaves could not vote, sit in the legislature, give evidence against whites or free-born persons of colour, serve on a jury, or participate fully in the economic life of the colony. Faced with limited prospects and an ambivalent racial identity, it is unsurprising, then, that the Augier sisters chose to supplement their incomes by participating in Jamaica's informal concubinage system":

Mary Augier became the mistress of William Tyndall (1693-1734), a merchant in Kingston, Jamaica, who was the son of Onesiphorus Tyndall (1657-1748), "a cadet of the Tyndall family of Melksham Court in Gloucestershire, who set out to make his fortune as a merchant in Bristol":
http://www.buildinghistory.org/bristol/banks.shtml
Tyndall made his fortune through the dry salt and Jamaican slave trade, so it's no surprise to find a son of his based in Jamaica. Onesiphorus was such a success - no doubt continually inspired by his first name, which means 'bringing profit' , that his eldest surviving son, another Onesiphorus Tyndall (1689-1757), William's older brother, became the senior founding partner of the first bank in Bristol, in 1750.
What the father-son Onesiphorus Tyndalls of Bristol thought of their mulatto grandchildren/nephews & nieces, is not recorded. William Tyndall had at least seven children with his freed mulatto mistress Mary Augier. In 1748, fourteen years after William Tyndall's death, Mary Augier and her seven children were granted 'the same rights and privileges with English subjects, born of white parents'.
"Official grants of white status to private individuals were incredibly rare in Jamaica and accorded to only the lightest-skinned and most well-to-do mulattoes...above three degrees removed from their african ancestor(s)". This means that Mary Augier's mother, John Augier's enslaved mistress, was also mulatto. During the entire 18th-century, there were only 128 bills passed by the Jamaican legislature granting white privileges to free people of colour.
Elizabeth Augier (born 1726), one of the daughters of William Tyndall & Mary Augier, bore five children with John Morse (c.1720-1781), a highly successful Jamaica planter and merchant with large landholdings totalling 8526 acres, who died in London. He was buried at St Mary Aldermanbury on 2 April 1781:

Each of John Morse's five children with Elizabeth Augier, the free mulatto lady granted the full status of a white Jamaican woman, relocated to England. The Morse family were unhappy with the legacies John had left to his illegitimate mixed-race children, and initiated a lengthy Chancery suit. Robert Morse became a lawyer and set out for India to pursue an ambitious legal and administrative career there. Two of his sisters, Anne Frances and Sarah, followed him there, probably with husband hunting in mind, as it was a more receptive environment for men and women of mixed race to find partners. These three Morse siblings had their portrait painted in about 1783 by John Zoffany:

Sarah and Anne Frances each married merchants of the East India Company in 1780. Anne Frances's husband, Nathaniel Middleton, has a bio in ODNB:

They were the parents of a large family of children, one of their daughters was Emily Middleton, born 18 May 1787, baptized 30 June 1787 at St Marylebone Parish Church, Westminster. She married 15 October 1804 at St George Hanover Square, Edward Jerningham of Painswick, a younger son of the 6th Baronet of Costessey Hall. Emily died in London 24 June 1822 of erysipelas, just 3 weeks after her husband died of the same infection. She was buried 28 June 1822 at St Augustine Chapel, Costessey Hall. Emily's portrait is here:

I find it fascinating and inspiring that two hundred years and six generations after a woman was born into slavery in a British West Indian colony, her great-great-great grandson would become the governor of another British West Indian colony.
