A collection of photographs by 19th century children's writer and mathematician Lewis Carroll, most of them of a female child model, has fetched $55,780 at a London auction, Phillips auctioneers said.

Carroll, whose real name was Charles Lutwidge Dodgson, was an enthusiastic photographer who wrote the classic children's stories "Alice's Adventures in Wonderland" and "Through the Looking Glass."Most of the 61 prints and 27 negatives sold Wednesday are of a family friend, child model Alexandra Kitchin, between the ages of five and 16. She was known as "Xie" by her family, and her godmother was Queen Alexandra. One of the bidders was Xie's great-granddaughter, Deryn Cowdy, a 26-year-old artist who paid $268 for a photograph of Xie at the age of 12 in July 1876.

The collection, which had been expected to sell for about $80,000, came on the market after a family disagreement over ownership, said Cowdy.
