The relationship between the Liddells and Dodgson suffered a sudden break in June 1863. There was no record of why the rift occurred, since the Liddells never openly spoke of it, and the single page in Dodgson's diary recording 27–29 June 1863 (which seems to cover the period in which it began) was missing;
[13] it has been speculated by biographers such as
Morton N. Cohen that Dodgson may have wanted to marry the 11-year-old Alice Liddell, and that this was the cause of the unexplained break with the family in June 1863.
[14] Alice Liddell's biographer, Anne Clark, writes that Alice's descendants were under the impression that Dodgson wanted to marry her, but that "Alice's parents expected a much better match for her." Clark argues that in Victorian England such arrangements were not as improbable as they might seem;
John Ruskin, for example, fell in love with a 12-year-old girl while Dodgson's younger brother sought to marry a 14-year-old, but postponed the wedding for six years.
