Mary Anne Evans:
(Nuneaton, 22 November 1819 – London, 22 December 1880), known by her pen name George Eliot, was an English writer and poet. She was also a journalist and translator. She is counted among the most important writers of the Victorian era.
Evans wrote seven novels: Adam Bede (1859), The Mill on the Floss (1860), Silas Marner (1861), Romola (1862-1863), Felix Holt, the Radical (1866), Middlemarch (1871-1872) and Daniel Deronda (1876). Her novels are known for their realism, psychological depth and sharp character dissection. Like her contemporaries Charles Dickens and Thomas Hardy, her background was in provincial England (the rural Midlands). Many of her works are set here.

Lovely autumn! My soul is wedded to it.

The sentence expresses a deep, almost intimate love of autumn. “My soul is wedded to it” means the speaker feels profoundly attached to the season—not literally married to it.
Origin and author:
The wording you quote appears to be a ‘paraphrase’, not the commonly cited original. The version attributed to George Eliot reads:
“Delicious autumn! My very soul is wedded to it, and if I were a bird I would fly about the earth seeking the successive autumns.”
So, ‘George Eliot is the traditional attribution’, but the search result confirms the wording only as a quotation being circulated under her name; it does not establish a primary source in her published work or letters. The shorter “Lovely autumn!” version may be a later adaptation.
Isn’t this a real autumn day? Exactly the quiet melancholy I love – bringing life and nature into harmony.
