Wonder about your Smith/Smyth line? We are arranging for DNA Test designed to "Reconstruct the Southern Smith Families."
It's a Y-chromosome DNA test limited to male Smith/Smyth  from an unbroken line of male Smith/Smyth. The test is targeted specifically at any Smith who has or thinks he or she has a line of Smiths that were in a southern state (ie, Virginia, Kentucky, South Carolina, North Carolina, Georgia, Alabama, West Virginia, etc)  at any time (the sheer numbers of Smiths in the world lead to this qualifier:) You must be a male Smith/Smyth or have a male Smith relative that could take the test as your representative.Acquaint yourself with DNA testing by visiting web site for Family Tree DNA, who is conducting the test:
If you qualify and wish to take the DNA Test (cheek swab), OR
(Be sure to look first at the 12 versus 25 versus 37 marker discussion) 
As part of the Smith/Smyth  Project, cost of the 12 marker DNA Test will be at a discounted price, down from  $149 to $99 -STRONGLY suggest that you get, however, the 25 marker test rather than 12 because of the sheer numbers of Smiths participating. In some cases, 12 markers shows a match but when 25 markers are used, the match falls apart.      
We have been getting a good Baseline of DNA from Smith/Smyth  with "documented" lineage from which Smith/Smyth  of "undocumented" lineage can seek DNA match. Results, identified only by kit number to protect privacy, will be posted on the internet for perusal.  If you've hit a stonewall in your Smith/Smyth research, DNA test might well be the answer in jump-starting your Smith/Smyth research. Your DNA may well match DNA from Smith/Smyth  who has documented lineage.
