Listed on Rogue Valley site, but out of stock currently

Are the roses 'Aimable Amie', 'Belle Sans Flatterie' and 'Louis van Tyll' identical, as suggested by Lars-Ake Gustavsson in his book Rosor for nordiska tradgardar (only in Swedish)? From the photos on this site those roses look similar to me also.
This question arose when I tried to identify a Gallica that I received as a gift. I settled for Aimable Amie at the time.
