Family History and Information

The Fitzwilliam family encompasses the The Fitzwilliam Diamond Company, several places in the English government, and associations with Capio Healthcare.

They are as blue-blooded as you can get without engaging in too much incest or interfering in too many royal marriages.

The family itself can be traced through the English government for several centuries. The first proper record that exists is of a John Fitzwilliam. He served in one of the earliest incarnations of the House of Lords in the 14th century, but there is vague record of Fitzwilliams before him, and his family was a branch of nobility in Wiltshire that extended into the 19th century, before the title was made extinct as the core of the family moved to South Africa. The first John Fitzwilliam was not the family member that established the name and authority, but the only evidence of this is that he was rich enough at birth to build a castle estate in Wiltshire, and that there was a castle estate before it (there are ruins). Baptismal records are missing for any other family members for some strange reason (likely there was a fire), but he may have had siblings.

(There are also references in royal lineages of the 11th, 12th and 12th centuries that show there to be FitzWilliams marrying into the families, though none became kings or queens or consorts.)

Since John Fitzwilliam, excellent records have been kept that show the family had a seat in the House of Lords for centuries. In the sixteenth and seventeenth centuries especially, many of the youngest members lived at court and were mistresses of the royal families, as well as intended wives. Caradoc Fitzwilliam frequently visited and it was there that he met his second wife, Sarah Brewer. Some of the ladies in the family were betrothed to royals of different families, such as the Habsburgs, though, again, none ever rose to king or queen (they were usually betrothed to princes or dukes not immediately in line for the throne, mostly because, while powerful, the Fitzwilliams wouldn't keep a dynasty in a family--they were useful for producing heirs).

Until the discovery of diamonds in South Africa in the last half of the nineteenth century, the family's main source of income came from their position as nobility with a well-respected and ancient name. They were in the first incarnation of Eton College, as well as exceedingly close to many of the kings and queens.

In the early 19th century, the family moved to help govern England's South African colony. The sons fought in many of the wars for England and settled down in the country. During the latter half of the nineteenth century, following Rhodes and all of the other diamond hunting rich kids, Lord Alexander and his eldest surviving sons set up their own mines and found some of the most prosperous areas along the Orange River, into what is now Namibia, as well as numerous other sites in South Africa (Cape Colony). Sir Jameson Fitzwilliam was especially interested in advancing technology that would make finding and sorting diamonds easier. He became the first CEO of the fledgling Fitzwilliam Diamond Company. His wife was insistent that they create jewelry fit for the galas they always attended. They became immensely popular with the royals due to their connections.

Jameson was the first male in the family not to go to the House of Lords or to take a place in the government. While he attended to his official duties as a Fitzwilliam, his primary focus was the diamonds. This has now led to there being two very distinct aspects of the family: one side diamonds, one side Parliament. While he inherited a title when he returned to England, he was more involved in his company.

His son, Sir Frederick Fitzwilliam, moved the company's headquarters to its present location (London), created the first shop in London, which has since moved to New Bond Street, and added a new shop in Cape Town, which has also moved. He helped improve the quality of the cut diamonds and in the 1920s, bought DeBeers, their main rival. This single move shot their fortune into the hundreds of millions of dollars (at the time). The American Depression had weakened the Oppenheimers enough for this to be a lucrative move for both families. By now, the Fitzwilliam reputation was unmatched in the diamond world. They had the monopoly on the diamonds and made certain to keep it that way by actively discovering new mines in other countries and keeping the ownership of each local so that there would be little friction between the mines. To this day, they continue to have the monopoly and are the major exporter of rough diamonds from London.

In the 1930s, their charity began, rounding the hard edges of a family that never knew poverty.

Thanks to Isabella Fitzwilliam, jewelry began to find its way into the celebrity circles and the company began to craft extremely intricate pieces that took years to complete. These were usually crowns and necklaces. Again, highly favored by royals in various countries.

Until the late 19th century, the family was as stiff and traditional as most are. Also, staunchly Protestant. However, after a conflict tore Lord Alexander's family apart, things began to change. Dynamics shifted. Though by tradition they remain a noble family, their attitudes are incredibly lax and the FDC side of the family keeps its nose out of government dealings. They do, however, attend royal ceremonies and parties and have retained a high reputation, especially as they create so many pieces for so many important people. You can't mess with the people supplying the royal jewels.

The family's popularity began to skyrocket with Sir Frederick Fitzwilliam and his wife, Lady Elizabeth Fitzwilliam. She was incredibly into selling herself and her family and playing in social circles with famous people of the day. Her descendants are the more famous of the Fitzwilliam family, especially Randolf's descendants. Randolf and Isabella Fitzwilliam were icons of their generation, with Isabella having been both England's sweetheart and America's sweetheart years before she married into the family. They were a playboy and a playgirl and posterchildren of a WWII generation. It was they who set up the charity. Isabella also starred in one Hollywood film about Florenz Ziegfeld, as she had been in the Follies. Her presence greatly endeared the public to their family and made other countries interested in them. Her children, grandchildren, and all of their children are the most famous family members now, and the ones furthest from government and politics.

Ultimately, the Fitzwilliams are in the circle of elite rich kids that are above most of the socialites trying to climb the latter. The sort of famous that gives them a blanket of invisibility. There are many exceptions, as their jewelry is a household name, despite most people not having their jewelry at all (just their diamonds), but for the most part, the Fitzwilliams are left well alone.

[edit]

Quirky Things

A well-kept secret of the family is that a great majority of the immediate family are angels.

Randolf and Isabella's descendants have a total net worth estimated at over sixty billion US dollars with about a third of that belonging to Charlie and his children (the other two thirds belonging to Scott and Alice). The company's revenue is over five billion a year and estimated to be worth even more than sixty billion, placing his family in the top three on the list of the top 400 billionaires, and making them the richest family in Britain.

They are known for being fans of white. White houses, white parties, white clothing. Charlie's two oldest daughters, Claire and Louise make the news more often, the latter for her insanity, the former for her charity (and her oldest son's shenanigans with his boyfriends).

Charity is a huge part of the Fitzwilliam lifestyle. In addition to Hope In Alms, they also run Jewelers for Children. They operate many free schools in South Africa and often hold auctions, benefits and participate in global fundraisers and awareness, especially for HIV/AIDS and poverty.

They do try to keep their personal lives personal, though there is some fascination with the kids, as none of them seem to ever grow older. In the 1980s, there was an interest in the three daughters of Charlie Fitzwilliam. Often referred to as the Sisters Fitzwilliam, they appeared in numerous pictorials and articles between 1985 and 1988. Again, the issue of an odd, supernaturally young look about them, not to mention just genuine beauty, gave people a reason to watch. Though the sisters themselves were rarely photographed candidly together (Louise was famous for dating celebrities and rich kids and even more famous for hating her sisters), people liked to envision them as some sort of perfect entity. Siren Sisters. Nothing could have been more odd.

Despite the careful consolidation of their lifestyle, critics do make claims that a family so rich, richer than the rest of the world, could not possibly understand the issues they are trying to overcome (ie, disease, poverty, etc.). Some claim that charity merely enhances their pristine image, as if they really did care, they could fund the entire country (which, if you refer to Hypothetical South Africa, is a good case). Those who actually know the family or are not inclined to immediately dismiss their generosity as a product of being rich make the claim that they invest personal time and energy, not just dollars, to their causes, and focus not on one group, but on all groups. Now, there will always be individuals in the family who don't care as much as the rest, but as a whole, they are hardworkers. The whole advancement of their fortune, which is a product of centuries, is because of their entrepreneurship, positive attitude and careful investment.

Their political stance is kept as private as their social stance, though they are known to be friends with Desmond Tutu.

Along Charlie's side of the family is a very distinct line of performing artists. The arts are very important to the family and they have a few ballet dancers, some professional, and other stage performers. They also donate heavily to different theatres and companies, including the Cape Town City Ballet and Artscape, and the Royal Ballet and Royal Opera House.

Nigel Fitzwilliam's line resumed its work in the government and still holds the family's seat in the House of Lords and has super fancy titles and all of that. But the whole of the family is still very much the epitome of British aristocracy, with a bit less of the stuffiness--and you can certainly thank jazz and liquor for loosening them up in the early 20th century.

In June of 2008, an article in the London Times attempted to blow the lid off the family's secret. As it's still June 2008, the results are yet unknown.

Peerages

For all intents and purposes of keeping my brain in tact, the Fitzwilliams are part of a peerage that doesn't actually exist anywhere but in this game. The peerage is now extinct in all of its forms, save one, meaning most of the titles are no longer inherited, but they've retained their votes and status, anyway.

Earl of Corsham, created 1112 - extinct 1397
Duke of Corsham, created 1399 - extinct 1690
Baron Fitzwilliam, created 1658 - extinct 1777
Viscount Corsham, created 1551 - extinct 1874
Duke of Wiltshire, created 1874, extinct 1904, reinstated 1931
