My grandfather immigrated from Croatia in 1910. He was Croatian. His given name was Ivan and his surname Skvorc, BUT... his family called him "Thithic". I was told that this was a "common" Croatian nick-name. However, looking on the internet, I have been unable to find ANY occurrence of Thithic except that there are people using it on Reddit and maybe Instagram or Facebook. One of those people was a Japanese girl. I'm trying to find out ANYTHING about that name associated with it being Croatian. Any help would be greatly appreciated.
