We are getting a good selection of Oliphants from America and in one case the confirmation that a person was from a particular line (which was suspected but not confirmed) and another, whose ancestry is unknown but whose DNA is clearly from a particular branch.

What we have found is that the DNA is complex and that if everyone is related, then it is not closely so. We need more Oliphants to be tested, so that the "bridge" DNAs can be found, linking people and groups together.
