Helena of Schleswig-Holstein wurde am 25 Mai 1846 in Buckingham Palace, Westminster, London, England, UK geboren. Sie war mit Prince Christian verheiratet. Sie starb am 9 Juni 1923 in London, England, UK.
Helena was a lively and outspoken child, and reacted against brotherly teasing by punching the bully on the nose. Her early talents included drawing. Lady Augusta Stanley, a lady-in-waiting to the Queen, commented favourably on the three-year-old Helena's artwork.
