Elizabeth of Wied was also seriously considered for Bertie, as was Anna of Hesse (sister of his eventual brother-in-law, Louis). Louise of Sweden was thought to be a good candidate, if not for that fact that she was ten years younger than Bertie.
Alfred pushed to marry Frederica (Lily) of Hanover, but Queen Victoria feared the blindness that was in Lily's family. QV didn't seem to understand that the blindness was not genetic. Alfred also wished that Bertie would refuse Alix of Denmark, so Alfred himself could marry her.
Arthur pursued another of the Hanover daughters - Marie, I believe?
Leopold considered many different brides; several refused him due to his health and other reasons. He, too, fell for Lily of Hanover; she had instead fallen in love with her father's equerry. Leopold helped the two to marry, and became a very close friend of Lily's for the rest of his life. Daisy Maynard was also considered, but she too fell for another man - Leopold's friend and former tutor. Again, he helped the two correspond, and they later married. Victoria of Baden, Calma of Schleswig-Holstein, and Elizabeth of Hesse-Cassel were all possibilities (Calma was the strongest candidate), but all refused Leopold on the basis of his health. By the time he met his eventual wife, Helen of Waldeck, poor Leopold was almost out of hope.
In many cases, it was Vicky who sought out and often arranged meetings for her brothers and their prospective wives.
