The title character of which novel marries a character called Sophia Western?

Sophia Western, fictional character, the beloved and, eventually, the wife of Tom Jones, a hero of Henry Fielding’s picaresque novel Tom Jones (1749).

The History of Tom Jones, a Foundling is a comic novel by English playwright and novelist Henry Fielding. It is both a Bildungsroman and a picaresque novel. It was first published on 28 February 1749 in London, and is among the earliest English prose works to be classified as a novel. It is the earliest novel mentioned by W. Somerset Maugham in his 1948 book Great Novelists and Their Novels among the ten best novels of the world. It totals 346,747 words divided into 18 smaller books, each preceded by a discursive chapter, often on topics unrelated to the book itself. It is dedicated to George Lyttleton.

The novel is highly organised, despite its length. Samuel Taylor Coleridge argued that it has one of the "three most perfect plots ever planned." It became a bestseller, with four editions being published in its first year alone.

Tom Jones is generally regarded as Fielding's greatest book and as a very influential English novel.
