If your Uncle has the surname of Davidson (i.e, he is a direct "male Davidson blood line") then he would be a candidate. I highly recommend the 37 marker test, since doing fewer markers (like 25, or especially only 12) can lead to "false positives" from time to time. Also, FTDNA is having a significant sale until the end of this month (August 2008), so you should join very soon (join through the link on www.davidsongenes.org). Once that link takes you to the FTDNA website "order form," there is a provision there where you can pay for the test (immediately by credit card or by having an invoice sent to your address) but where the testing kit is mailed directly to your uncle. If you have any questions or comments, please let me know. Important Note: The author of this message may not be subscribed to this list.
