My mother (who is only related by marriage to the family in question) recounted a story that my great-grandmother's little brother died in the first World War when he and a group of fellow young officers were on town leave, and a Serbian soldier came along and shot him in the back.
Now, my mother has a much better memory for these sorts of family stories than most people, me included, but I still can't place much weight on any of the details (not least because they come through the filter of my memory of what my mother said). So let's just say that the young man was a soldier, possibly an officer, in the Austro-Hungarian army during WWI, and died during the war.
The more certain details: he was born on Dec. 3, 1886 in Budapest, Hungary, and was given the names Béla Ferencz at his baptism on Dec. 9 (https://www.familysearch.org/ark:/61903/3:1:9Q97-YS85-5R1). His father was Gaiter János, a restauranteur originally from Pornó, Vas county, Hungary, and his mother was Steidl Teréz, who came from Mór, Fejér county, Hungary. He is listed among the survivors on his father's funeral notice in 1912 (https://www.familysearch.org/ark:/61903/3:1:S3HT-6QK3-X6J?i=858&wc=M6WV-FNG%3A101520501%2C101520502&cc=1542666), but there are no clues as to his occupation at that time.
Both the OCR-based search at the Austrian State Library (http://anno.onb.ac.at/anno-suche/#searchMode=complex&title=Verlustliste&dateMode=period&yearFrom=1914&yearTo=1914&from=21) and the human-based index at GenTeam (https://www.genteam.eu/) only turn up one Gaiter in the Verlustliste: a rather detail-poor entry among the officers in issue number 9, dated Aug. 31, 1914, indicating that Adalbert Gaiter, a cadet in the reserves of infantry regiment 53 company 2, had died (http://anno.onb.ac.at/cgi-content/anno?aid=vll&datum=19140831&seite=4&zoom=60).
Other relevant tidbits: The name Adalbert (or Albert) was sometimes used as a German "translation" of the native Hungarian name Béla.
Béla's elder sister spoke fluent German as well as her native Hungarian. This came in handy when she became the cantor-teacher's wife in Harta, a Danube Schwabian village about 80 km (50 mi) south of Budapest. (The marriage was in 1902.)
My question is: what is known about the unit and rank and whatnot given in the Loss List? Can any of it exclude (or much less likely, verify) the entry as a match to my relative? Is there any hope of more information somewhere to go with such an anemic entry in the Loss Lists?
Edited to add more detail about what it is I'm trying to find out:
The Loss List entry, anemic as it is, gives a unit and subunit, and comes with a date. Is there someplace where I can look up information about that unit, such as where it was based or where the people in it mostly came from, and what it was doing (where it was) in the summer of 1914?
Alternately, is there an archive somewhere that would have files about the members of Austria-Hungary's infantry regiment 53, company 2, where I could look up Adalbert Gaiter's birthdate or mother's name?
