Maybe you'll have better luck with them. If you wish we can help you with some translation into Polish.

KREKLAU: most likely from dialectal verb krekać (the sound a duck, crow, capercaillie, etc. gives off).

KOTLENGA/KOTLĘGA: from kociół (cookpot, boiler); possibly originatred to indicate the helper of a koltarz (pot-maker, coppersmith).
