No, the Schleswig-Holstein's weren't her favorites for obvious reasons. She could be rather cruel, in fact, to Helena Victoria regarding her looks. (Reminiscent of her and Marie F's treatment of their sister-in-law Louise. They had a bit of the 'mean girls' in them.) Edward VII also wasn't particularly close to his sister Helena. However, George and Mary were close to both female cousins and they were hard-working members of the royal family throughout his reign. Unlike her cousin Toria, Helena Victoria never struck me as particularly embittered by her life--at least, there are no stories relating to her feeling so. She seems like she kept up a busy, productive and full-of-friends life.
