Zientara
ZIENTARA: This fairly popular Polish surname is sometimes mistakenly believed to be derived from zięć (son-in-law). More likely than not it traces its origin to German names such as Sinter, Sindbert, Sindhart, etc. In Old German sind meant way, road or travel.
An alternate spelling is Ziętara which looks even more Polish, hence few people suspect its distant Germanic roots.
KWIATKOWSKI: root-word kwiat (flower). A typical toponmyic from such localities as Kwiatków and Kwiatkowo (Flowerton, Floralville).
