So your set up doesn't have the Principled Bsdf node but instead the Subsurface one so is that the way to go for human skin?  Keep it simple?  My render turned out allot better but now the skin looks a little flat and there is no input for the specular map so I guess that's not needed?  

By the way, thank you so much for your help!  :-) 

The PrincipledBsdf node was added later to P12 shortly after Blender introduced it into its software.  It is not absolutely needed.  But where the Cycle node is concerned, you need to build up the shader until you get what you want to render—trial and error.  The PrincipledBsdf is an incorporation of all those nodes into one.
