I thought this might be of some interest to you ladies, since a lot of people are no longer in the areas where their loved ones are buried. It's pretty easy to look up if you know their names and the state they are buried in. They also have a place that you can click on for people that are requesting anyone in that area to take a picture of a grave that they are searching for.

This is my Grandmother on my Dad's side of the family, she died when I was only 7 years old, but I fondly remember going to their house on Sundays and she would give me orange soda in a glass bottle and a little bag of Fritos.
