No where in the world except for where you live would be able to pronounce or write this surname correctly. It would most likely have been shortened to something more easy to say and write.
I did that making the name shorter by deleting the first letters h then l then i then s ...until finally I got to KOVSKY which is where I think this is how it would be in North and South America. Could also be SNIKOVSKY but I checked each name olne by one and there is no one listed in ANY NAME in the Argentina Telephone Directory for all of that country. Sorry Petertimber
