Mysterious girl? – Even though it's fair to assume that Christina is the photographer's daughter, some uncertainty remains. "We do not know who Christina is," Colin Harding, Curator of Photographs and Photographic Technology at the National Media Museum, said.
"There is no record of Lt Mervyn O'Gorman and his wife, Florence, having any children as far as I have been able to find. There is a census record of a woman named Christina O'Gorman living in Dublin, who was born in the 1890s.
"This would make her about the same age as the model in these photos, and we do know Mervyn O'Gorman had family links in Ireland. It is possible it may be the same person and she's a relative, but we can't say for sure."
