Albert and Victoria chose the names Louisa Caroline Alberta named after her paternal grandmother, Princess Louise of Saxe-Gotha-Altenburg. She was baptized on 13 May 1848 in Buckingham Palace's private chapel by John Bird Sumner, the Archbishop of Canterbury. Though she was christened Louisa at the service, she was invariably known as Louise throughout her life. Her godparents were Duke Gustav of Mecklenburg-Schwerin (her paternal great-great-uncle, for whom Prince Albert stood proxy); the Duchess of Saxe-Meiningen (for whom her great-aunt Queen Adelaide stood proxy); and the Hereditary Grand Duchess of Mecklenburg-Strelitz (her first cousin once-removed, for whom the Duchess of Cambridge stood proxy). During the ceremony, the Duchess of Gloucester, one of the few children of King George III who was still alive, forgot where she was, and suddenly got up in the middle of the service and knelt at the queen's feet, much to the queen's horror.
