text: https://en.wikipedia.org/wiki/Hiiu_Parish says:
  Hiiu Parish was established by merging the town of Kärdla [OSM relation 351941] (former urban municipality) and Kõrgessaare Parish [350685] after the municipal elections held on 20 October 2013.
  Hiiu is also refered by Eurostats as NUTS3:EE004, LAU1:0039, LAU2:0204
  Being a user, not a mapper, I would appreciate if someone could merge the two.
