Forgive me but I have to ask. When you say 70's and 80's, what century do you mean? 1900's or 1800's?
As far as where the table came from, all I can say for sure is the midwest usa. Illinois, Wisconsin, or Indiana. That's where my parents lived. If I had to guess, it came from a pair of old ladies in the north suburbs of chicago, whom my Dad was a caretaker for. All I remember of them is that they were REALLY old back in the 70's, both widowed and wealthy. Maybe of German decent, or somewere middle european. I was only 10 years old at the time, but I remember they had a heavy accent. I know thier geneology has nothing to do with this table, but that's all I remember.
