Goldmark's quintet was written in late 1914, according to Juilliard's online library catalog - they have a copy of the manuscript, every movement of which is dated (it was written in Vienna between September 27 and November 16, 1914, more or less.) So your guess of 1914 is right on the money...
So yes, sometimes one can find out these things-- but not from publication date
alone 
Sorry- correction:
"Each movement dated at end, with movements 2-4 also signed, written variously in Unterach, Gmunden, and Wien, Österreich between September 27 and November 16, 1914"
