I want to add something to reassure everyone that the info in the database is correct. Wikipedia can be a misleading source because the contributors are not necessarily experts on the subject. So, here's the story on the 'Peace' rose. I'll try to boil it down to a short paragraph.
Francois Meilland did hybridize a rose in 1939 and did name it after his mother, Madame A. Meilland. World War II then intervened. He sent the rose out of France shortly before the Nazi occupation in four diplomatic pouches. Its name then was '3-35-40.' Three of the pouches were lost and only the one sent to the United States survived. After the fall of the Vichy Government in 1944, Meilland wrote to Field Marshal Viscount Alanbrooke and offered to name the rose after him in gratitude for the liberation of Paris by the Allies. The field marshal declined the honor, saying the rose should be named 'Peace,' and that was the name when it was introduced in 1945 and it is now the official exhibition name of the rose. So, although it was called 'Madame A. Meilland' or 'Madame Antoine Meilland' for a brief time, it was also called '3-35-40,' 'Gioia,' and 'Gloria Dei.' None of these is the official name of the rose.
