I also always find this strange about Helen and her marriage prospects...She was young,for me beautiful at that time and very,very wealthy...she schould be more ahead of the rest of European princesses,but she ended up in a love match with a Prince...
One more thing about Helen-she found herself in a love match,but reacted just like her mother when her daughter Olga wanted to marry Prince Paul of Yugoslavia,as she found that a descedant of the Demidov family is about to make aliance with an ''Imperial'' family which she didn't find plesing for her imperial dignity(just like her mother)...but after that his money ''made the way'' to her heart!
