I am not sure whether there is a connection with this info, but I found the name al-Kubash, a.o. used in Africa (I have no further details). In Arabic al-Kubash (or Alkubash) الكبش means "ram".
I also found a posting of somebody, who was researching the name Kubash / Kubas. His ancestor with this name came from Czechoslovakia to the USA in the beginning of the 20th century. Here's the link:

Transliterations of the name in:
Magyar: Kubášek (Kubas)
Hindi: कुबस (Kubas)
Persian: س (Qbs)((Kubas)
Russian: кубас (Kubas)
Servian: кубаш (Kubash) кубас (Kubas)
Slovakian: Kubaš
I hope this helps to find out in which direction to search for more info.
