I guess the next step is to see if we have any male Davenports, Northern or Southern, or from the British Isles, Canada, Australia or New Zealand, who would be interested in participating in a Y DNA study. Unless there is some fund raising, each person would have to pay for his own test or secure a sponsor. You can look at the following page to get an idea of the costs involved: http://freepages.genealogy.rootsweb.com/~scperkins/BallDNA.html The links from the post this morning have more details on the tests and the reasons to do this.
