Family Dining Table

This is a dining table passed down from my grandfather. I do not know anything about it. My father says it came from Germany and is a couple of hundred years old. I honestly do not know. I am having it restored. I never plan to sell it. I hope to pass it down one day. I would like to know where it originated and how old it is. It has 3 leafs that go in the table. I have 7 chairs. I think there originally was 8. It also has the middle leg missing from the table which would give it 5 legs. There is alot of detail in the designs on the chairs. Any info would be greatly appreciated and will help me learn a little more about this peice I got from my Grandfather. Thanks! BTW, Love the show!
