avis de décès allemands

Stillnfried's record in the Kriegsstammrollen on Ancestry mentions only the Iron Cross 2nd Class, awarded on 8 Dec 1914. German records are usually pretty accurate, so it's likely your other medals aren't his - unless perhaps they were awarded posthumously?

Ferdinand Stellnfried was born on 12 September 1886 at Stöttham, Chieming, the son of Maria Stellnfried nee Berger of Übersee. (His father was deceased and his name is not given.) Ferdinand was married to Anna nee Gnadl and had one child, but that information is marked with a cross to indicate that the child subsequently died. His occupation is given as Distrikts-Straßenwärter, district roadmender, and his place of residence as Reit im Winkl, which is the parish that includes Entfelden.
His name is on the war memorial at Reit i/W: http://www.kriegstot...ktuell&Id=28626

He served his compulsory military service from 1906 to 1908 with 2nd Company, Bavarian Infantry Regiment No.2.

He was called up on 5 Aug 1914 to 10th Company, RIR 1, with whom he remained for his entire period of service. He was promoted Gefreiter on 25/11/14 and Unteroffizier on 11/1/15. It's also noted that he was trained on Minenwerfer.
There's a very long list of the campaigns and battles he was involved in - probably the entire history of RIR 10. He was never wounded.

Concerning his death, the record merely states "Missing since 9/4/17". And this was published in Bavarian Verlustliste (Casualty List) No.345 of 9/6/17.
However, under this in the record is the note: "laut [Verlustliste] 426 gefallen G.+". Casualty List No.426 was published after the war, in June 1919, but it's not available on Ancestry nor yet on the Verlustlisten Project at http://wiki-de.genea...rster_Weltkrieg so we can't see what it actually says, but I understand "G.+" to mean "died as PoW" (G=Gefangenschaft). It sounds like he died behind Canadian lines and is body was identified and buried by them at the time, but the German authorities did not discover this until after the war.
