Enola Holmes is not adopted. She is the biological daughter of Mycroft and Eudoria Holmes. This information is explicitly stated in the books and movies.
- The Enola Holmes Mysteries book series by Nancy Springer features Enola as the youngest sibling of Sherlock and Mycroft Holmes.
- The Netflix film adaptations, starring Millie Bobby Brown, also portray Enola as the biological daughter of the Holmes family.
While Enola's independent spirit and unconventional upbringing might give the impression of an adopted child, the narrative consistently portrays her as a member of the Holmes family by blood.
