Not likely to be of German descent, as most, if not all of what were left here were wiped out by the mites. Those that may have survived were not likely to find German drones to mate with, therefore feral survivors are if anything.........Mutts.
Most likely you have a swarm of Carniolans, but a slim chance of Caucasians, both of which have dark characteristics. My Carni's have dark abdomens with grey stripes, no gold to them whatsoever, and the queens are solid black or dark mocha. Caucasians are similar, but I haven't seen hives of any in a few years, and don't recall their markings.
