It was thought surprising that in Sonnet clii., in which Shakespeare calls himself forsworn because he loves his lady although married to another, he also states expressly that she too is married, calling her "twice forsworn," since she has not only broken her "bed-vow," but broken her "new faith" to Shakespeare himself. It seemed difficult to reconcile this with the fact that Mrs. Fitton ("Mistress" in those days being applicable to unmarried no less than to married women) was always called by her father's name. She was married in 1607 to a certain William Polwheele, with whom she appears to have had a love-intrigue before the wedding. After the death of her husband she was married a second time to John Lougher. However, it must now be pointed out that a work, published in 1897, which for the first time gave a trustworthy account of Mary Fitton's life, has rendered it excessively improbable that she should be identical with the Dark Lady of the Sonnets. The title of the work is: _Gossip from a Muniment-Room, being Passages in the lives of Anne and Mary Fitton_, 1574-1618; it is published by Lady Newdigate-Newdegate, who is married to a descendant of the elder sister, Anne Fitton, and it contains many interesting letters to this lady, with other communications from the family-archives. Here it is proved--in spite of Tyler's attempted contradiction--that the two well-preserved portraits of Mary Fitton at Arbury show that she was not dark at all, but had a light complexion, brown hair, and grey eyes.
