I have found that scanning something done in light pencil with the scanner set to grayscale as dark as possible, then adjusting the curves in photoshop helps. I don't do the contrast until later on as you are trying to capture something already light in tone.
Alternatively I have done it old school, and used a photocopier set at the darkest settings. You'll wind up with an overall dark image, but the pencil lines will still be there.
Then it can be adjusted in photoshop with adjusting the brightness, contrast, and curves.
Good luck,

You may need to consult with your county's archives if they have scanning services or your state's archives and possibly bring the documents to them for scanning using their equipment.
