One of my Belgian anscestors familyname is Ikats or Ikots (Icots). (See familysearch) . It can be written in several ways. I know as fact that the first who came to “Belgium” (Spanish Netherlands called that time) was a soldier in the Austrian Hungarian army. Difficult to find the place of his origin. It is a very rare name. I found the name in Slovakia, Hungary, Russia,Ukraine, Croatia and Serbia.
It maybe is a Rysin name.
