That's exactly right. If you ask kurds in areas outside west Iran, they mostly(50%+) tell you that they have Armenians or Assyrian grandma. Basically, they are raped by kurdish men, during civil unrests of Ottoman collapse and so called Armenian genocide. Some persians or arabs may not know this, but it is a very well known fact that every one from neighboring regions of kurds know it very well. The first wave of sunni kurds, were sent to north Iraq, during a population exchange of shias and sunnis between Safavids and Ottomans. Safavids received shia turks from Anatolia, and gave sunni kurds to Ottomans. very good deal for Safavids indeed
