Krys,
it is an absolute coincidence! I looked at a site about your posiolek and on the Russian site someone just posted a reference --I mean posted today regarding this particular place. It is at a site ref below.
this refers to someone who was there and was rehabilitated.
There are several Polish names in the Memory Book for this oblast.
I am not sure if your Mom remembers any other names in that locality, but it is Verkhnyaya Klyuchanka , Dobryansky rayon, Permskaya oblast;and there is a very good map of a forest place of Klyuchy --posiolek. One has to be certain of this location and this can only be so if your Mom might have mentioned another village nearby.
