Hello Robert, we have already cleared some specific things in emails and here’s what I would like to publish for forum.
Synjak, Hungarian Szinyak, German Blaubad, now is village of city type with 200 of inhabitants. Interestingly, in 1910 its population was 131 of people, mostly Germans. So it didn’t change radically for last 100 years.
It’s known as little spa city and also as area with big number of mineral water springs of supreme quality. First mention about these springs was found in 1783, stationary spa was built in 1838 by Earl Philip Franz von Schönborn.
Now they have great spa “Synjak” there with a lot of medical services. Nature around is astonishing, I saw it personally when I was there.
In genealogic terms, Synjak is referenced to Mukachevo and Chynadijevo / Szentmiklós. Munkacs has big collection of Roman-Catholic records, rare city can boast of it.
