Hmmm... I found this very interesting. I married into the Shirosky name and to my knowledge, the name was "made up" because when the "Shirosky's" migrated to the U.S./Canada, a teacher could not pronounce the correct name, therefore, gave them the Shirosky name. I have been told that if there is a Shirosky out there, we are all related because of this. Yet, I have never heard of the people you are inquiring about.
