For CWd Clarrisa Wright Dixon has been suggested a few times - although her name is actually Dickson Wright.
(Actually, her full name was Clarissa Theresa Philomena Aileen Mary Josephine Agnes Elsie Trilby Louise Esmerelda Dickson Wright)
FOR the CWD one it may be worth checking whether the setter has announced a correction. There can't be many fairly common 8 letter forenames beginning with C- Charlene, Clarissa, Chrissie.
The W could be another forename or a surname like Watson, Wright, Walker, Wilson.
Last could be Dixon, Derby...
