I want to know the answer to the following question:
The polish believed szlachta derived from the name of who?
All the background I'm provided with is that "Poles of the 17th century assumed that "szlachta" came from the German "schlachten" ("to slaughter" or "to butcher"); also suggestive is the German "Schlacht" ("battle").". Is that enough to answer the question?
Answer: no
