John, The answer is, you possibly are, but since other McLoughlin's are also close to the Modal STR values and are tested negative for M222, then only passing an M222 SNP test will give you the answer to your question - it's as simple as that. In regards to past members of the list advocating for not SNP testing, and feeling that being close to the Modal values was enough, you'll find - if you search the archives - that I highly contested this view when it was first mooted on this list, as I still do now. Again I think that finding a group with similar STR values and having members both positive and negative for M222 is huge, as this helps us home in on where the SNP possibly first arose. Obviously since we are talking about a SNP, then one unique individual had this mutation first and it spread through his descendants. Of course unless he packed his bags and left his home area, then other relatives around him would still be Pre-M222 or negative for M2222. So finding people who are Pre-M222 is almost as usefull as finding people who are M222+.
