Thank you for the replies.
This is all I have:
Liste der angekommenen und abgereisten P. T. Curgäste in Carlsbad im Jahre Periodical Page
There is a reference to a Herr Geistlicher Iwan Welihorski.
There are other references under the same title, but in Issue 1.7.1902.
My great-grandfather was an Iwan, so I am interested.
There are other references but under different surname deriviatives, namely Wielhorsky, Wielhorski and Velehorski.
This is as far as I can get when I search the website mentioned in the Kramerius website - a periodical number and reference.
Any help gratefully received.
