I thumb through my few books with patterns, which is mostly Fostoria and Cambridge, and came up short. Which does not surprise me too much, since you said they came from Europe. Europe Crystal is a whole different ballpark, here we mostly see Fostoria and Cambridge with Acid Etched patterns on the surface. Not sure what Europe companies was known for this. It might help to get a picture of the Stem, Stems are just important in finding the maker as the etching is. I will see if I can find some names of popular crystal Glass makers in Europe that is known for this style.
