Graveyards would have nothing for you. The graves would be long gone. The standard is 75 years for graves before they are re-used and the stones removed.
Records that old would also not be in the church, but the church building itself could very well originate from the time your ancestors lived there so is worth a visit. The graveyard would surround the church.
Records that old are kept in the regional archives...but they are also all available online for free.
