I strongly encourage all members who have not already done so to transfer their results to Ysearch. This will enable you to find Gormans who have tested with different labs, or who have not chosen to join the Gorman DNA Project, and can therefore potentially augment your list of DNA matches.  If you are a current Family Tree DNA member, there is a link to automatically transfer your results to Ysearch on your "Y-DNA Matches" tab on your FTDNA personal page.  In the middle of the page, at the bottom of the box called "Additional possibilities for searching matches," there is a link to "Click here to upload to Ysearch.org."

I highly recommend that anybody who has only tested at the 12-marker level (FTDNA's YDNA12 test) should upgrade to a minimum of 37 markers. 67 markers is much better, and most serious family researchers will eventually upgrade to this level, so you can save a lot of time by starting with this upgrade, rather than upgrading in steps.  There are several reasons for this recommendation:

(1) It is possible to be a perfect 12/12 match with somebody, yet not be closely related to them (or even distantly related).  It is a common occurrence for people who were previously 12/12 matches to "lose the match" when they test more markers, because they only happened to match on the first 12 markers by random chance (or genetic "convergence").  A close match with 37 or 67 markers is far less likely to happen by chance, and an upgrade is the best way to confirm a tentative 12-marker match. 

(2) The converse is also possible, that a mismatch on a 12-marker test (causing somebody to fail to appear at all in your list of matches) can turn into a match when more markers are tested.  This has personally happened to me with at least one of the Gorman project participants. There is another project member right now, who does not appear at all in my results list at FTDNA, due to his disparate 12-marker test results, who I have confirmed to be a distant relative of mine after examining his pedigree.  Using an extreme example, if somebody is only a 9/12 match on a 12-marker test (75% of the markers match), they will not show up at all on the list of matches on your FTDNA personal page.  If that person then upgrades to a 67-marker test, and the remaining markers are a perfect match, they now become a 64/67 match (96% of the markers match), which is highly significant and indicates a near-certain relation.  Though an example this extreme is not especially likely to happen with numbers like these, it does serve to illustrate a possible outcome.  Had I stopped testing at 12 markers, I would have never discovered any DNA matches, and I would now be wondering why nobody in the world seems to be my kin!

(3) The more markers you test, the more accurately you can narrow down the confidence level for the time to your most recent common ancestor (TMRCA).  While testing more markers will not increase your relatedness to somebody per se, it will help you say with a greater confidence level, that, for example, you shared a common ancestor with him in the last 5 generations.  For example, instead of the chance of a common ancestor within that timeframe being only 50%, you might be able to increase those odds to, say, 90%, if the markers continue to match as more markers are tested.  Please be aware, however, that estimates of TMRCA's are only statistical tools, and no degree of testing will allow you to identify the year when your common ancestor lived.  That's where supplementing your DNA data with conventional paper trails come into play.

If you have already been Y-DNA tested to 37 or more markers, then you may wish to consider getting what is called a "SNP" test (called a "Deep-Clade Test" at FTDNA).  If you have not been SNP tested, your haplogroup assignment (e.g., R1b1) is only a prediction.  A SNP test will confirm this assignment with certainty, and may also classify you to a much more specific haplogroup (e.g., R1b1b2a) than you were predicted to be.  A haplogroup assignment is another very powerful tool for evaluating potential DNA matches.  If you are a perfect 12/12 match with somebody, but they have been SNP tested as a different haplogroup from you, then they cannot be related to you in a genealogical time frame, and the 12/12 "match" is just a random convergence of mutations.  While SNP testing cannot prove matches in and of itself, it can and will eliminate false matches.  If your funds are limited, then I recommend first spending your money on upgrading to 37 or 67 markers, before having a SNP test done.

Not a lot of Gormans have been DNA tested yet, and it is very important to help get as many new members into the project as possible, to help tease apart the relationships between the various lineages shown in the results page.  If you discover a DNA match to you, please encourage him to join the project!  Furthermore, if your paper trail research has identified any distant cousins and you are able to make contact with them (I can help suggest ways to discover and make contact with such people), please encourage them to join.  This will help you confirm that they are indeed kin (paper trails can be very misleading at times!), and will also help determine where mutations in your lineage may have occurred.  For the latter purpose, the more distant the cousin, the better.  Please note that new members get heavily discounted FTDNA tests by ordering through the Gorman project.
