No one could read Dorothy Wordsworth’s journal of her life with her brother at Dove Cottage, Grasmere, without realising that her love for him was uncommonly passionate. Even someone with a superficial knowledge of William Wordsworth’s life and works will know that he felt his sister to be so much a part of him that he used her observations, and even her words, in poems he wrote at the time.
… Where’er my footsteps turned,
Her Voice was like a hidden Bird that sang;
The thought of her was like a flash of light
Or an unseen companionship, a breath
Or fragrance independent of the wind.
