I am not a member of your family. I helped because I could and I must have had some free time that day. I AM the volunteer coordinator of the Alexander DNA Project: http://www.familytreedna.com/public/alexander-y-dna
You can see the Alexander ancestries of all 250+ members at: http://www.familytreedna.com/public/alexander-y-dna/default....
If you want a brief paper that simply explains DNA testing that I put together, you can write me at email@example.com
