I'm familiar with The Cooley Genealogy and have been in touch with the family association. I don't have the book but I do have access to it. I'm sure you know that Joseph was the grandson of Joseph Cooley and Kaziah Casey. It's believed that the elder Joseph was a son of John Cooley of Stokes county NC. I have a website devoted to John at johncooley.net.
I'll email you separately for your URL. I'm looking forward to seeing your site.
