If your ancestors were farmers, try to find out who owned the farm. After 1832, you can check the Cadastre, before that time you can check real estate tax records or transport deeds in court records.
Not many farmers owned their own farm. If they rented the farm from a rich or noble family, the archives of that family may have survived and may have records about your family. If they were serfs, the serf registers of the overlord may provide more information.
For an example, read about two tenancy contracts from the 1700s, and the information contained in them.
