Aimable Amie, gallica/provins , she is very full > 41 petals

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.

Is it thornless (without prickles, for the purist)?
Was it used as a rootstock in the late 19th or early 20th century?
