Looking for some help...

Well it has been a long time since I have posted anything on this blog.  You see after my mom passed away in August I had a difficult time coping.  I let a lot of things slide this blog being one of them.  I am happy to say that I am coping better now and hope to revive this blog.  For now I would like some help dating a piece of furniture.  Over the last few months my sisters and I have been sorting out my Mom and Dad's belongings.  (My Dad passed away in 1996). My parents lived in my father's family home which he inherited when his parents passed.  There are generations of belongings to sort through.  This buffet is a piece of furniture that had sat in my parents living room for as long as any of my sisters and I can remember.  I have a vague memory of my parents saying that it had belonged to my grandparents on my fathers side.  I have looked over the piece and I can't find a manufacturer's mark or anything that could help date it.  A friend at the library where I work suggested I do a google image search but it didn't help.  Does anyone have any ideas how I could find out how old it could be?
