Your husband's grandfather was from the region known as TRANSYLVANIA, the major city in which is the city called in Hungarian KOLOZSVÁR, in German KLAUSENBURG, and today in Romanian CLUJ.(If you're familiar with Dracula, you're familiar with Transylvania.)
Your husband's grandfather was from the village called in Hungarian ALSÓUCSA (Lower Ucsa), in German UNTERUTSCHA, and today in Romanian UCEA DE JOS (note correct spelling), which is very near to the city called in Hungarian BRASSÓ, in German KRONSTADT, and today in Romanian BRASOV.
The 1907 passenger arrival record shows his last place of residence as having been Alsóucsa, the village's Hungarian name, and you found something which shows last residence as Ucea de Jos, the village's Romanian name.But it is one and the same village.
Until 1918, Transylvania was part of HUNGARY.Following World War I and the break-up of the vast Austro-Hungarian Empire, Transylvania was awarded to ROMANIA and remains part of Romania today.Transylvania is an ethnically mixed region.
