antique secretary desk

This is a secretary desk that have been in my family for years. It has 6 drawers, 2 hidden spaces, one central compartment and another compartment on the desk. Also has 3 big drawers on the lower section. You can open the main door, which is the desk itself. Height is 3 feet and 4 inches. It's approximately the same width. And about 19 inches of depth. I don't know where this furniture comes from or the date... I want to know if it's possible to have that info and much it's worth. Thanks.

Good
