Hi David,      There is a strong Horvath line in Darowa.  I checked, but I could not find your Lorenz.  However, you might find more Horvaths in the surrounding villages.  It might be worth asking for a look-up in Gizeladorf, Bakowa, Nitzkydorf, Lugoj, etc.       I am sorry that I could not be of more help.
