Welcome to the Cress DNA Project. Our purpose is to provide that next step, when the paper trail ends, in that search for your elusive ancestor. DNA testing provides an alternative to wasting time and money (less cost than a research trip) in finding clues to your lineage and overcoming that brick wall. If you wonder whether you might share a common ancestor with another Cress (or similar surname such as Kress, Grass, etc) DNA testing can provide answers.
