Trying to authencate the information on my desk

I recently bought this large desk at an auction. I'm trying to find out more about this piece. We love it, but I like the history of things. The dimensions are 29" (D) x 71" (W) x 30" (H). It is large. I'm assuming its a writing desk because of the front drawer, but it's the size of many tables. I also assume it's pretty old by looking at the paper lining the drawer. Any information is greatly appreciated!! Thank you, Chris
