The name is illussive. I found 1 Tichere, 2 Ticherer, 1 Tichermann, 1 Tichert, 4 Tisher, 9 Tichert, 10 Tiker in Germany. France seems to always have a variation of a sort also. I also got an email from a Tysor in Nebraska, where most of them seem to be over here. He said they came over here from Czchosavakia and the name was pronounced Tikor. I wonder if the Tiser in Hungary are Tikor? I also got an email from a Tyser in Scottland. He said the name is a mystery but he suspected its origin is Scandinavian, and that the Tyser clan was originally well known in the shipping industry in Scottland. That would make a lot of sense. The Vikings invaded England, Ireland, Scottland, Northern France, Germany. Obviously the name has changed in both pronunciation and spelling. However, if there is a connection the names should have a common meaning. Ti in England was a geographical name for someone living on a small island, by a river or a common pasture. My cousin said a German told her it referred to a small lake in Germany. But I come up with no translation (from Altavista translator) for any of the variations of spelling. Still, we might be getting somewhere.
