I did some basic research which lead to finding your family tree, at that point I stopped research.Post the link to your tree in the future with your posting, it helps volunteers see what you have already found to eliminate providing duplication.I really don't see you having trouble finding family history.You might need to further describe what you are seeking.I would also suggest posting on the Lincoln County Message Board on Rootsweb.com... More view and volunteers.
