I'm in the process of having my son-in-law tested. There is no Allen name study on FamilyTreeDNA, which is, to my knowledge, the organization with the largest number of name studies going. If there is still no Allen study going by the time I get my results, I may start one. You may want to keep your eye out there. The web page is: http://www.familytreedna.comhttp://www.familytreedna.com. It will take several months.
