What county or counties are the two locations in that your referring to? I know there were Griders in Johnson Co., AR that were related to Moses Grider wife Mary Powell; some in Clay Co., AR that we think are related to Silas Grider (a brother to Moses); there are some Griders in AR that are related to John McGavock Grider the WWI aviator. They lived near the plantation of Sans Souci which I believe is near Grider, AR. I've seen listings for an Granville J. Grider/Gryder too. Some descendants of Valentine Gryder too were in AR. How far back do you have info on your Grider line? I could help fit you into my database tree. I am putting together a book on the Grider/Gryder family and would like to make sure I have your info included. Hope you'll get in touch. Below is my e-mail and home mailing address. Especially looking for old stories and photos to put in the book.
