leon sounds jewish but not chuk.

Answer 2

It is actually a Polish name. Mainly non Jews have the name.  Some Jews adopted it when Poland required everyone to have a last name. Mainly non Jews have the name.  

The only name that is really Jewish is Cohen and Levi. You won't find many non Jews with those names.

sounds polish or russian

yes. Many Ashkenazi Jewish last names have Slavic suffixes like Agranovic, Anahovich, or Smilaynsky. This last name sounds Ukranian, so the person with this last name might be Ukranian, not Jewish.
