Fanny Trollope: the life and adventures of a clever woman

by Pamela Neville-Sington, Viking pounds 20

Social histories of the early Victorian period have a tendency to play down the importance of the woman writer. No doubt, the literary sisterhood of the 1840s was a heterodox crowd - it included the down-at- heel poets satirised in Pendennis as well as genuine best-sellers - but at its upper level it was a force to be reckoned with. Mrs Gore, to take a representative example, was an influential figure in Victorian society for 20 years, and Thackeray professed himself flattered by a rumour that she was the author of the then anonymous Vanity Fair.

In some ways Fanny Trollope stands at the head of a literary grouping whose significance was always likely to be more than literary. The publisher Whittaker gave her pounds 400 for her first novel, The Refugee in America, in 1832. Domestic Manners of the Americans, which had established her reputation earlier in the same year, was one of the great pioneer exercises in transatlantic disparagement; its influence lasted deep into the later 19th century. Dickens had a copy to hand when he wrote his American Notes, while Anthony Trollope, visiting Ohio a good 40 years after his mother's stay, found that her reputation survived intact.

Like many another Victorian literary output, Mrs Trollope's 35 novels and half-dozen travel books were the product of necessity. If the series of financial disasters racked up by her moody barrister husband Thomas Anthony seem over-familiar to the readers of Victorian novels, it is because Anthony put several of them into his own fiction: the descent of the bailiffs on the Roberts's vicarage in Framley Parsonage mirrors a real-life depredation on the Trollopes' Harrow farmhouse. Irascible, quarrelsome, fatalistic ("The touch of his hand seemed to create failure" according to Anthony), poisoned by the mercury he took for his painful headaches, Trollope senior eventually became a millstone around his wife's neck. Her American trip in the late 1820s, originally to join a commune of simple-lifers, was a transparent attempt to escape from an increasingly irksome and impoverished home. Returning after four years of fruitless commercial endeavour - including a Cincinatti entertainment palace that ate up what remained of her capital - she found her husband nearly bankrupt. Despite the success of Domestic Manners, the family fled to the continent to escape paterfamilias's arraignment for debt.

Amid tribulation and tragedy - husband and two children died within the space of a single year - Mrs Trollope wrote indefatigably on, elbowed her way into polite literary society, struck advantageous bargains with sharp contemporary publishers like Bentley and Colburn, and rapidly became a household name. Among the many marks of her intelligence, as Pamela Neville-Sington shows, was a shrewd eye for the market. Her first two books had been dramatisations of her American experiences, but the third (The Abbess, 1833) exploited a period vogue for the Gothic romance. Thereafter, the tide flowed relentlessly on, only coming to a halt with Fashionable Life in 1856, two years short of her 80th birthday.

Fanny Trollope: The Life and Adventures of a Clever Woman (Neville-Sington's edition of Domestic Manners is published simultaneously in Penguin Classics at pounds 8.99) is a thoroughly worthy take on this extraordinary career, a touch unadventurously written in its early stages, perhaps, but picking up no end - as it could scarcely fail to do - when covering the American scenes. If there are two slight irritations, they are the biographer's dogged attempts to weave Fanny's early life into the social circles inhabited by Jane Austen, and her belief that almost every scenario in the novels has some parallel in her subject's own life. Nothing wrong with the life/art nexus, of course, especially when the source material is thin, but between pages 49 and 50, for example there are no fewer than five descriptions of life chez Trollope which turn out to have been filched from the Trollope oeuvre.

On the other hand, Neville-Sington is good on the sheer effervescence of Fanny's character: it is easy to believe, from the personality sketched here, that the literary powers were there from the first (in fact, Fanny did make one or two pre-crash attempts at a novel) and wanted only the stimulus of approaching ruin to stir them into action. There are also some shrewd glimpses of the young Anthony (who resented not being taken to America) skulking round his father's chambers or, as a hobbledehoy clerk, bringing home his own debts for maternal settlement. Here, it seems fairly evident, the money fixations of his own Autobiography have their source.
