Welcome to Wikitree, Flavius!
Do you live in Banat or Transylvania? Then it is possible that your German/Bavarian ancestors had the name Hanisch/Harnisch, as C-H already wrote.
In any case, your name is wrong here. If your surname is Haneși and your first name is Flavius, then you have entered it upside down when you registered. You should edit your LNAB (Last Name at Birth) and Proper First Name with the correct names.
To be able to add profiles, you need to upgrade to the family membership--no charge. To do this click on upgrade on either your navigation or profile page.
