Silber is silver. I wonder what "kleit" is? A clinical term for what organ?
“kleid” is dress — I think it means “silver dress” (although in her case it should be something else)
I have read that many of the family names involving gold-, silber-, fein-, or -stein stem from a list of names that Jewish families in Germany were forced to purchase during the middle ages; a sort of punitive tax. The richer-sounding names, e.g., Goldstein or Feingold, cost more.
