Jane Austen, early Charles Dickens, Thomas Love Peacock all published around that time.
Frankly, my advice is not to try and create a pastiche of English of the period. It is possible if you have been totally immersed in it (Rose Macaulay wrote a brilliant novel set in the 17th century, using syntax of the period, but she was extremely knowledgable about the writers of the period, even producing a poem that fooled experts). Otherwise the language tends to seem forced.
