George Eliot (really a woman) wrote pastoral romances (the Austen kind). Not novels but the poetry of Elizabeth Barrett Browning and Christina Rosetti is worth a look (Emily Bronte-esque sweeping passion), Mary Shelley for something more supernatural ('Frankenstein' being her most famous work). Louisa May Alcott for something a little less taxing (she wrote 'Little Women') or something a bit different from the usual run is Lydia Maria Child, an American author who was a bit hard-line and Gaskell-esque; wrote about early America and the indigenous population.
For male writers there's always Wilde (sublime aestheticism at its best), Dickens (actually very readable even though he's got a bit of a stuffy reputation-socialism in a Gaskell vein), George Gissing (very allegorical but 'New Grub Street' is well worth a look), Thomas Hardy (pastoral doom and gloom - start with 'Tess' if you're going there!) and Bram Stoker for something a bit spooky (he wrote 'Dracula' but also did some good novels based on Irish folklore)
Hope this helps & happy reading!
