Thanks for your help. Again, with knowledge beforehand I can now see “Murmansk.”
Perhaps you can help a little more. I have only a superficial understanding of the prisons/work camps in the Soviet Russia during the 30s. With internet searches I’ve found that in Arkhangelsk Oblast, Kotlas shows up. Within Murmansk Oblast, the place that keeps showing up is the Solovki prison camp (later Solovki prison), located on the Solovetsky Islands in the White Sea. Do you know if there were other prisons/work camps in those Oblasts?
