Hi Sandra, the Vance Family Association has a website at http://vancefamilyassociation.org
. It was founded about 30 years ago to study and collect the origins and history of the Vance surname (and variants) and has collected and published a lot of research by their members in their regular newsletters. There is an annual membership fee which you can find on their website.
There is also an online blog for the VFA at http://vancehistoryonline.blogspot.com
with regular articles on topics related to the Vances, and a Facebook page for the blog if you search for "Vance History Online" on Facebook.
