Hello Anni,
I couldn’t find either spelling in the Kreutzstätten family book. I also checked the List of Surnames in the back of the book for anything that looked similar, but still could not find this family. Amalia Heilemasz or Herlemasz is not listed either.
If you want to send the record you are working from, I’d be happy to take a look and see if I can read the spelling. Or let me know if there is anything else I can check for you.
mfg,
—Karen
