"I have noticed on a Eurocart map that there is now a village called Kavalar at the, I belive, western shore of Lake Weissensee (about ten miles southwest of Spittal) & would like to find out more about this villages origins, since I believe it was named after our family."
most times familynames can come about the places they lived - not vice versa.
the name Kavalar has slavic (slovenian)orgin and comes about occupation not a place:
kovalo, nakovalo = anvil (Amboß in german)
kovati = forge (schmieden in german)
Kovac = Smith (Schmid in german)
name-variants are Schmied, Schmidt, Kobau, Kovac and so on.
WHERE should this place called Kavalar be?
