Gregovich
There are three major wand makers in Europe, Ollivander of England is one, and Gregoritch of Germany is another. Just as Ollivander supplied wands specifically to Hogwarts (some foreign wizards also came here), Grigovitch's main customer was Durmstrang School of Witchcraft and Wizardry.
Gregovich once collected the famous Elder Wand (Elder Wand), which was later stolen by Gellert Grindelwald. But many years later, Voldemort came to Grigovitch again because of the Elder Wand. This time Grigovitch was not so lucky and was brutally killed by Voldemort.
As for the last of the three wand makers, neither the novel nor the extras have ever mentioned it. However, since Ollivander corresponds to Hogwarts and Gregorovitch corresponds to Durmstrang, then the other wand maker is most likely from France, mainly for students of Beauxbatons School of Witchcraft and Wizardry. magic wand.
