Serbian name version “Irmenjhaza” (Ирмењхаза) was used as the official name. In 1921, the Serbian name was changed to “Jermenovci” (Јерменовци). It was, however, still unofficially called Ürményháza by local Hungarians. The population grew until 1931 despite emigration to faraway lands but remained a predominantly ethnic Hungarian enclave to this date with its bilingual village folk. After World War II, the population of the village decreased. The oil surveying began in 1951. The first oil well became operational on 9 November 1952, while the continuous production began in 1956, uninterrupted until today (2018). The name and its origin Built on dried and reclaimed vacant state property marshlands, the village was named “Ürmenhausen” / “Ürményháza” / “Irmenjhaza” (Ирмењхаза) in 1817, in deference to its virtual founding father, the Hungarian nobleman and Crown Counsellor Ferenc Ürményi (1780–1880), director of the Treasury’s Crown Lands Department in Temeschwar / Timișoara (in today’s Romania). The German, Hungarian and Serbian names for the village were officially used in various time periods. The older Serbian name “Irmenjhaza” (Ирмењхаза) was changed to “Jermenovci” (Јерменовци) in 1921.
