Not an ancestor. Objective C and C++ were seperately developed, in
different parts of the C community, and so far as I know there was
little or no communication or cross-fertilization. (Well, there
is a creature called 'Objective-C++', but I don't know much about
that, though I get the impression it is little used.)
Objective-C's object model is dynamicly typed, strongly based on
smalltalk ideas. C++'s object model is staticly typed, strongly
based on Simula-67 ideas. They come from different branches of the
OO tree.

It was / is much loved by the NeXT community, and it did languish for
some years while NeXT did. MacOS X revived it, and the GNUStep
people never stopped using it. So it isn't likely to vanish
anytime soon. However I doubt it will ever be as
widespread as C++, much less C.
If you wish to use the GNUStep desktop framework, which as far as I
understand (I haven't played with it much under freebsd) works
great in freebsd, you'll need Objective-C. I can't think of
anything else that needs it, however.
