Some SNPs have only been found in a single person (L319) or a family (L1226) and for the time being have been included in their parent group. Another singleton M379 has not been included as we do not have enough information to place it within the M223 tree.
Under investigation: L1272, L1409, Z166, Z180, Z185, Z187, Z2055-Z2101 and various SNP from the ZS series.
The Project Administrator always recommends that Project Members spend $39 to know for sure their terminal SNP.
If they are not interested in testing more STR markers at the moment, at least they will be able to immediately apply the results they have so far to their research if they know their terminal SNP. Separately testing individual STR markers to still have to guess whether one is positive or negative for a given SNP is actually more expensive than testing the SNP itself. This guessing will also have damaging effects on one's genealogical research. We all know that research time is precious and we'd rather not waste it on Ghost Most Recent Common Ancestors who never actually existed.
In general, SNP recommendations are made at the headings of specific subgroups. You will find your subgroup by doing a search for your kit number or surname in our Project Results page.
Simply test the SNP at the end of your subgroup header tag and, if negative, follow the heading backwards until you find your terminal SNP. For example, take the subgroup Cont2b Group1. The tag reads: 22.214.171.124.1.2.1- M223>....>Z161>L801, Z76>Z183>CTS1977>P95 which is a shortened version for M223>CTS616/CTS9183>CTS10057/CTS10100>Z161>L801/Z76>Z183>CTS1977>P95. If you were Cont2b Group1, you would test P95. If negative, you would then test CTS1977, if negative, then Z183, if negative, then either L801 or Z76, which are phyloequivalent. Once you get a positive result, you know that is your terminal SNP for the time being, until new discoveries are made. Only individuals who share your terminal SNP should be considered in your genealogical research. Knowing your terminal SNP will go a long way in terms of determining who is actually related to you.

As researchers, we tend to get impatient because we don't get any close matches. That is not anyone's fault - it simply has to do with how rare a specific line of descent is and with how many children belonging to this line have survived to the present. If you cannot find matches, you can either wait until individuals related to you eventually test or you can draft them. We all have similar frustrations and have to find ways to work around them.
Our project has about 1,200 members. As one can easily see, most of these members have different surnames so it is not humanly possible for the project administrators to really aid in private genealogical goals. We guide members in terms of establishing their terminal SNP's, then applying this to their matches and finding clues to their genealogical puzzles this way. And we try to get SNP's that are useful to our community accepted by ISOGG and FT DNA, so they are added to the list of recommended SNP's, more tests can be ordered and more connections between haplotypes, lineages and surnames may be found.
