The mix up with 'Dorothy Lambert' appears to go a long ways back. There is a question about it in the AHS Robin archives from 2005. If an imposter, possibly 'Something' from looking at the images above, has been sold all this time and prior to 2005 it would make sense that there are a lot of incorrectly labeled 'Dorothy Lambert' plants out there.
Your images of 'Something' look similar to this image on E and B Farm's site and to the ones here at ATP.

Funny how 'Something' seems to twist one petal in many of the images, even the ones here in the database.
The image on the Tranquil Lakes website appears to match the description for 'Dorothy Lambert' along with the daysong link mainstreet found.
