Very early for this type of work, from right after Victoria became queen. Julia Pardoe wrote at least two other books on Ottoman Turkish topics. She traveled to what is now Turkey in 1835 with her father. Her Wikipedia entry doesn’t say when she left but she died in London, England from insomnia and liver issues in 1862.

Also, I didn’t find this book by myself. Like the last blog post about touring Scotland in 1907, I found it here https://www.kaaterskillbooks.com/ and then found a scanned version on the Internet Archive website.
