LDS batches & sheets are what the person has submitted for LDS ordinances, and I have never seen that there is any useful information (like WHERE they got their information), nor any more than what is given in the IGI reference. If you want, you could order the film from your local branch Family History Library, and view the film there, but you will be out $4.50, and know no more than you what you now have. I use IGI listings to indicate that someone, sometime, somehow, actually did find out a date. Knowing that there is something somewhere makes the search easier. You can, however, know that an IGI Extracted Record (mentioned at the bottom of the listing), is taken from an actual public record, and thae film # for that record is listed. Good luck Mabry Benson
