I like Kastautas! Do you (or any of your relatives) happen to know the meaning of it? Maybe it is a more modern form of
Kestutis? I can't find anything about it on Google, only that Kastautas seems to be more common as a surname than a first name.
EDIT: Oh, just found something. ;) The Wikipedia article below mentions Kestautas as being related to
Kestutis. Kestautas differs just one letter from Kastautas, so it's possible that Kastautas is indeed etymologically related to
Kestutis.
