Function needed to recursively search a directory for a named subdirectory

Normally I would just do this myself, but I am a bit pressed for time :)

I need a function that will locate a named subdirectory within a parent directory, and have as its
return value the path string to the subdirectory.

Here is an example.

Assume the following directories exist:

c:\Start here\Location 1\Team 1\Alice
c:\Start here\Location 1\Team 1\Ben
c:\Start here\Location 1\Team 1\Charlene
c:\Start here\Location 1\Team 2\David
c:\Start here\Location 1\Team 2\Ernie
c:\Start here\Location 1\Team 2\Frances
c:\Start here\Location 2\Team 3\George
c:\Start here\Location 2\Team 3\Harry
c:\Start here\Location 2\Team 3\Ivana
c:\Start here\Location 2\Team 4\John
c:\Start here\Location 2\Team 4\Karla
c:\Start here\Location 2\Team 4\Lance
c:\Start here\Location 3\Team 5\Mary
c:\Start here\Location 3\Team 5\Neville
c:\Start here\Location 3\Team 5\Opal
c:\Start here\Location 3\Team 6\Quentin
c:\Start here\Location 3\Team 6\Rachel
c:\Start here\Location 3\Team 6\Stephen

All of the people's folders exist somewhere in c:\Start here, or in one of the folder's "descendants".

I need a function to which I could pass arguments like "c:\Start here" and "Quentin", and then the function
would search recursively through c:\Start here and its descendants until it finds
c:\Start here\Location 3\Team 6\Quentin, and would return the string "c:\Start here\Location 3\Team 6\Quentin".

Thanks,

Patrick
