Missing diaries

At least four complete volumes and around seven pages of text are missing from Dodgson's 13 diaries. The loss of the volumes remains unexplained; the pages have been removed by an unknown hand. Most scholars assume that the diary material was removed by family members in the interests of preserving the family name, but this has not been proven. Except for one page, material is missing from his diaries for the period between 1853 and 1863 (when Dodgson was 21–31 years old). During this period, Dodgson began experiencing great mental and spiritual anguish and confessing to an overwhelming sense of his own sin. This was also the period of time when he composed his extensive love poetry, leading to speculation that the poems were autobiographical.

Many theories have been put forward to explain the missing material. A popular explanation for one missing page (27 June 1863) is that it might have been torn out to conceal a proposal of marriage on that day by Dodgson to the 11-year-old Alice Liddell. However, there has never been any evidence to suggest this, and a paper suggests evidence to the contrary which was discovered by Karoline Leach in the Dodgson family archive in 1996.

This paper is known as the "cut pages in diary" document. Carroll's nephew Philip Dodgson Jacques reports that he wrote it well after Carroll's death, based on information from his aunts, who destroyed two diary pages, including the one for 27 June 1863. Jacques did not see the pages himself. The summary for 27 June states that Mrs. Liddell told Dodgson there was gossip circulating about him and the Liddell family's governess, as well as about his relationship with "Ina", presumably Alice's older sister Lorina Liddell. The "break" with the Liddell family that occurred soon after was presumably in response to this gossip. Without evidence, Leach suggests an alternative interpretation; Lorina was also the name of Alice Liddell's mother. What is deemed most crucial and surprising is the document seems to imply that Dodgson's break with the family was not connected with Alice at all. Until a primary source is discovered, the events of 27 June 1863 will remain in doubt; however, a 1930 letter from the younger Lorina Liddell to Alice may shed light on the matter. Reporting an interview with an early Dodgson biographer, she wrote:

I said his manner became too affectionate to you as you grew older, and that mother spoke to him about it, and that offended him so he ceased coming to visit us again – as one had to find some reason for all intercourse ceasing... Mr. D used to take you on his knee... I did not say that.
