Jews in Austria and Germany (and in relevant parts of partitioned Poland) got their surnames administratively assigned by the government. Therefore most western Ashkenazi Jews have two-part names with popular parts including "Baum", "Berg", "Feld", "Gold", "Rosen", "Apfel" etc. Here is interesting article about this, though only in polish.
It just sounded German as fuck with apfelbaum, which is what I also assumed the original name was before her family came to America (or whatever).
But your point is taken and I will edit that portion out.
