I have a rather old picture that is so small it is hard to see the face of the subject. When I try to enlarge the picture, it just blurs and sharpening does not seem to help. Is there another way to do this? I am fairly new to photoshop.

If its a small image it will not contain much detail and PS enlarges(upsamples) by adding pixels based on the information in the adjacent pixels.
For example, if you have a black pixel against a white pixel, PS will insert a grey pixel between them which leads to a softening of the image (blurring) When working with small images you need to scan them at the highest resolution possible and even with this, you cannot create detail that is absent to start with.

While all this is fundamentally correct, Scott Kelby, in his book on CS2, p108, suggests a "Rule-Breaking Resizing for Poster-Sized Prints," that may worth trying.

Not familiar with the book, but would that be anything to do with upsampling in increments?
Chris Cox (Adobe software engineer) has indicated that it is actualy worse to upspample in increments since (as I recall) every small error introduced by upsampling gets multiplied.
10% increments were the vogue before the days of bicubic smoother was added to the PS mix, ISTR.
Genuine fractals may help, try googling for it.
