Herenyi seems to mean Hungarian.
I have access to one (Hungarian).
Only ~ 7 million people speak Hungarian and the language is unlike anything else in Europe or elsewhere.
I'll ask.

It turns that (once again) I was wrong.
My friend says that the marking means "Gothard" (First name) "Herenyi" (last name) "Stirling" possibly street name, "Szombathely" (Town).
Gothard would be an antiquated first name. and Herenyi means "from Hereny", which is a suburb of Szombathely, but would be a last name for sure.
It happens that my friend's brother lives in that very town and might look into the matter.
I have searched for a possible Stirling street in Szombathely, but I could not find one. However, I imagine that very few old street names would have survived the 20th century.
I'll report if I hear something new.
All the best,
