Is there a list somewhere of what common (BD and similar companies) generic overseas frame models match to the brand-name bikes they are knock-offs of?

I'm particularly interested in the Specialized Roubaix, which I think I saw in generic form somewhere with the Zertz inserts. But also I would have thought that there are people informed enough to match up frame specs and say "Aha! That's the same as a XYZ PedalHarder!". Any list or website?

Tx!
