Germanic names are Germanic, so they are IE (although I've read theories that say otherwise). The only fenno-ugric names on the map are Sapmi and Asodat.
Try to divide the words into phrases, it should be easier this way, Swebotraustastamnoz ("Swebian Trust(alliance)", IIRC) is no more (or less) difficult than your typical modern german panzerkampfwagen or schnellfeuerwaffe :)
