Larry, Try the organization that publishes Ancestree... Is it the Greater Omaha Gen. Soc.? Or some other? Perhaps the Nebraska State Historical Society has back issues. They are online at www.nebraskahistory.com (or .org, I forget!). I have a couple old issues of Ancestree that I ordered from someone online. I don't think it was ebay, but some issues were definitely for sale. I can't remember where. Good luck, Laura
