Louise became engaged to the Marquess of Lorne on 3 October 1870 while they were visiting Balmoral. Lorne was invited to Balmoral Castle in Scotland, and accompanied Louise, the Lord Chancellor, Lord Hatherley and Queen Victoria's lady-in-waiting Lady Ely on a drive. Later that day, Louise returned and announced to the queen that Lorne had "spoken of his devotion" to Louise, and she accepted his proposal in the knowledge of the queen's approval. The queen later gave Lady Ely a bracelet to mark the occasion.
