A home renovation turning up secrets from a hundred years ago.

FOX's Lilian Woo reports:

Electrician German Martinez was helping renovate a home in North Carolina when he uncovered a compartment hidden behind a layer of drywall and another of plaster and wood.

The find: a tin box and ash covered leather bound books, among the treasure trove of historic documents, papers signed by presidents Andrew Jackson and Martin Van Buren.

The Asheville Citizen Times reporting that the papers of Thomas W. Patton, the house's original builder, included presidential signatures on land grants to Patton, who was a captain in the Confederate Army.

Its unclear who hid the correspondence in the historic Patton Parker House which an attorney bought last fall.
