For girls, Honor, Verity, Faith, Joy, Pearl, Faye, May, Iris, Amber, Wren, Anna, Bonnie, Seren, Tara, Cara, Cora, Ruth, Sara, Lorna, Mairead, Mary, Nia, Mair (it's Welsh), Leah, Eve, Kate, Grace and Rose (although my Grace gets people calling her 'Gracie'...).
For boys, the only ones that I can think of off the top of my head are the ones called things like John, Owen, George, Tom, Elis, Miles, Felix, Joe, Mark, Adam, Luke, Josh. In one family's case, their parents went for short names because they didn't want them to be shortened further! I also vaguely knew a Charles who insisted on being called Charles, rather than any of the short forms.
