I have only the first volume which my sister inherited after my grandfather's passing. The book contains the original research performed on the Veach families as of 1974 but they do go into a bit of detail. I'm only starting to get into reading the book and figuring out how to go about tracing my family from that era. Volumes 2 and 3 should contain more recent research as well as family files that have been reported to our historical society (the website that I mentioned). I'll better understand those volumes better once I purchase them. While reading the first volume, I'll keep an eye out for Indiana Veaches.
