Here is another Jernigan family website. Now this website was active when I first started researching the Jarnagins. It was a very active community with a e-mail list and everything.
I don't think it exists anymore except as old webpages, but you can find much info here on current family researchers.
The e-mail addresses might be out dated on some of the people but some of the e-mail addresses might still be valid.http://home.att.net/~mboots/Jernigan_Homepage/XXV.htm
