Similar to other European countries, cemeteries in Poland may not be the best source to find ancestors farther back in time. Cemetery fees must be paid and when they are no longer being currently maintained, will then be replaced by newer grave markers. Oftentimes the cemeteries are directly at the site of the church grounds. However, in many cases they are apart from the church grounds, as well. They are often carefully maintained with planted flowers or plants, watered and cared for by relatives of the deceased. You will also see candles at the gravesites, as well.
