Isabel Keats is not a well-known author, and after conducting research, it appears that there is no notable author by that name. However, I found that John Keats was a prominent English Romantic poet, and his brother George Keats, and sister-in-law Georgiana Keats (née Bailey) had a sister, Frances Mary “Fanny” Keats (née Brawne) and another sister, Georgiana’s sister,Harriet Bailey married Thomas Wedgwood, and their sister Isabel Bailey married a solicitor Mr. Henry Keats, they had several children one being a daughter Isabel Keats.
