Anthony Trollope
Trollope is well known for his series of novels set in the imaginary county of Barsetshire.  His first novel was published in 1847 and The Warden, the first Barsetshire novel, in 1855. The rest of the series were published during the next 12 years: The Barchester Chronicles (1857), Doctor Thorne (1858), Framley Parsonage (1861), The Small House at Allington (1864), and The Last Chronicle of Barset (1867). Barsetshire is imagined as a county in southwest England. The county town is Barchester, which is the seat of the Bishop of Barchester.
