Hello everyone ~
Due to the message below, I've had to update our DNA Tables. All the
464 a, b, c, & d Marker numbers for all our Participants are now updated
on the Table to reflect this change at the FTDNA company and the
University of Arizona. This update does NOT effect any relationships on
our Table, but must be made to keep consistent with future Participants
results. The letter below is provided for your information - if you're
interested in it. (If you don't see your numbers changed, then be sure
to "refresh" the page.)
