Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

[Moved from]: Looking for info on the name HOROCHEIFSKA...

Hello, I am from the USA. My mother was born in Poland. She's past away many years ago. Her maiden name was Horochiefska. Honestly I'm not real sure that is the correct spelling. My mother was a concentration camp survivor and I often have suspected that she altered the spelling so no one would go after any of her remaining family. She came from a town called L'VOV. Then after the war it was L'WOW. I might have that backwards. Anyway any help would be appreciated. Thanks
