How do I put an already running CHILD process under nohup

My question is very similar to that posted in: How do I put an already-running process under nohup?

Say I execute foo.sh from my command line, and it in turn executes another shell script, and so on. For example:

foo.sh
 \_ bar.sh
    \_ baz.sh

Now I press Ctrl+Z to suspend "foo.sh". It is listed in my "jobs -l".

How do I disown baz.sh so that it is no longer a grandchild of foo.sh? If I type "disown" then only foo.sh is disowned from its parent, which isn't exactly what i want. I'd like to kill off the foo.sh and bar.sh processes and only be left with baz.sh.

My current workaround is to "kill -18" (resume) baz.sh and go on with my work, but I would prefer to kill the aforementioned processes. Thanks.

Use ps to get the PID of bar.sh, and kill it.
