did prolog have any children that lived?

A 10+ year old book I'm reading mentions MU-prolog, NU-prolog and Prolog III
as more declarative possible successors to Prolog. I wonder what became of
them?

AFAIK, MU- and NU-Prolog are no longer maintained (in the sense of
evolving, being extended, enhanced ...).
http://www.cs.mu.oz.au/~lee/src/ says (about MU-Prolog): primarily of
historical interest.

Prolog III has a successor: Prolog VI.

In some sense, Erlang is a child of Prolog that still lives (very much).

Maybe Mercury could pass as a Prolog child - but the father of Mercury
might disagree :-)
