Some significant statistics: Kokocinski is the 62,772nd most popular last name (surname) in the United States [CBN].
The German phone book lists about 42 entries (www.teleauskunft.de), an US-american lists 52 (www.infospace.com) and every once in awhile other Kokocinski’s from Germany, France, Poland and the United States run into these pages…
The web page “HowManyOfMe” currently states, that there are over 150 people in the U.S. with the last name Kokocinski.
looking at the ending, the name sounds like a typical name from the polish area – but there is no clear meaning ko-ko – that’s a sound a hen makes (in Poland) kokoszka – a sitting hen, which just laid an egg kokoszyc – to boss (with a bit of a negative meaning)
But then there is Kokopelli, a religious figure of the native Americans in the southwest of North America:
here koko means wood and pilau stands for hump the stories of the Anasazi describe him as a hunchbacked wandering god of fertility and joy, bringing springtime into the lands and playing cheerful music
