Although those records can be a great source for information, don't count on it 100%. Try to get more than one source from different places. Eleven years ago, a cemetery had my brother listed as his father unknown and his mother deceased. Both was the wrong information. I called them right away and it was corrected. Many times it's the second hand people who can get the information mixed up, not the informant. Also, I just received my mother's certificate Saturday and there is wrong information on it. Checking information as soon as possible will help people in the future. It can be corrected before the time to do so. Just thought I'd mention some of the problems of mistakes that can happen. Anna
