Looking for a short story by Hesse about Jure Grando, a vampire

[AntiMatt3r]

I'm doing some research, and a couple of articles make reference to a story by Hesse (or possibly a story in an anthology edited by Hesse). The story concerns Jure Grando, a vampire from (what is now) Croatia. The story was based on a "real" folklore vampire, and was first recorded by Baron Valvasor in his 15-tome work, The Glory of the Duchy of Carniola. From here, it was included in The Rhone's Antiquarian (?) - any information about this would be welcome, as I can't find anything about it in English.

This was where Hesse picked up the story, and either re-wrote it or included it in an anthology. This looks like the best candidate:
Spuk--Hexengeschichten-Rheinischen-Antiquarius-Hermann-Hesse

Is it in here? Any other information? Any English translations?

Thanks.

I found very little about it in German.
Spuk- und Hexengeschichten aus dem »Rheinischen
Antiquarius, edited by Hermann Hesse is available in German at several antiquarians but I didn´t find any content description.
It also wasn´t included in the two short biographies of Hesse I consulted.
