Jeremy Clarkson is not a man given to considered opinion. So it is not surprising that, when he was asked to research his family's history, his response was abrupt: 'Too boring to bother with', he said. He could not understand why anyone would be interested in finding out about the lives of his ancestors.
Jeremy was aware that one of his forebears had invented the Kilner jar, a receptacle for preserved fruit that is still popular in homes today. But he was completely unaware that the story of the Kilners, his maternal ancestors, was one of 'rags to riches and back to rags'. This information piqued his curiosity, and he was persuaded to pursue his family history a little further.
Family legend had it that the Kilners fell into bankruptcy. Jeremy's mother had often told him that another firm had stolen the patent for the jar, while there were rumours that the Kilners failed to register the patent in the first place. Whatever the truth, Jeremy understood that he might have been born into extraordinary wealth except for this mysterious reversal of fortunes.
Researches into John Kilner, Jeremy's great-great-great grandfather, born in 1792, revealed that he was once an employee in a glass factory. He set up a glassworks with friends and through thrift and skill turned the business into a massive success. Industrialisation and growing prosperity increased the demand for the production of glasses, jars and bottles, and soon John possessed two factories in south Yorkshire.
He died in 1857, and the firm was taken over by his four sons, George (Jeremy's great-great grandfather), William, John and Caleb. Each learned their trade on the factory floor, and the firm, then known as Kilner Brothers, continued to thrive and flourish.
Caleb, the youngest, was given the job of opening a London warehouse for the firm. This warehouse was used to store Kilner products so they could be transported all over the world.
One of the firm's factories won the only medal awarded to British glass-bottle makers at the Great International Exhibition held in London in 1862. Then in the 1870s and 1880s, the business won medals and awards in Paris, Philadelphia, Sydney and Melbourne. The Kilners were at the summit of their trade.
Small family firms in Britain came under increasing pressure in the early 20th century, due to competition from cheap imports, and some firms had to merge to survive. One such merger created United Glass Bottle, a conglomeration of six glassware firms. They bought the Kilner patents when the firm fell into decline.
When Caleb Kilner had died he'd left the equivalent of millions of pounds in his will, most of which went to his son, George, and son-in-law, Harry Smethurst, but records show that neither of these died with much money to their name. So the question is, where did the money go?
Harry Smethurst - or 'Flash Harry' as he was known in the local pit village of Denaby - married Jeremy's great grandmother Annie Kilner, but was not involved with the glassworks. He was an architect, and is known to have designed many of the buildings in Denaby, as well as buildings for the Kilner brothers.
Harry and Annie liked to show off their wealth, and may have frittered much of the fortune. Rumour had it that they'd spent some of the inherited money on a motor car, around 1901, which must have made Harry one of the first men in south Yorkshire to own a car. Some money remained, but when Annie died she disinherited her daughter (Jeremy's grandmother) Gwendoline.
Research revealed that when the factory closed there was a family rift over how the proceeds of the closure should be divided, and Gwendoline sided with her cousin, causing estrangement from her parents. The money instead all passed on to her brother, Tom.
So Jeremy found out why he might have been born rich, but wasn't, and discovered an interest in common with his great grandfather, Harry. Whether he takes things further, though, is anyone's guess.
