Look on your keyboard to find it. By the way, a link is one of those underlined text do-hickeys that you click on to get somewhere else. Don't be embarrassed if you didn't know that.

Some people coordinate several counties.
This means the county coordinator is ready to hand the reins over to some other poor, unsuspecting soul. Maintaining a site is a job, folks, and we owe a lot to these people. Each of these pages is different and has different amounts of information. What is included is pretty much decided by the county coordinator and how much time he or she is willing to put into the project. Some pages have family surnames listed and you can check and see if anyone is researching a family with your surname in that particular county.
