Setting up a Ysearch ID

To get maximum benefit from having your DNA tested, all Irish Type III members should set up a Ysearch record at www.ysearch.org if you have not already done so. This will allow you to compare your results (haplotype) with all the others in the largest database available to everyone, perhaps finding others with similar surnames that you have common heritage with. It will help others find you too. If you are a FTDNA customer, your results at 12, 25, 37 or 67 markers can be automatically entered at Ysearch from your Personal Page. When you have published your results publicly on Ysearch, I am then able to include them in the results page of the 'Irish Type III' website. I will not post your results on the website unless you have a Ysearch record as I will always respect your right to privacy. We will all, however, get the greatest gains by being prepared to share our information and hence get more and better matches to one another.

If you do set up a Ysearch ID and have tested elsewhere, or have ordered any advanced markers from FTDNA, please be aware that there are several markers that may need conversion.

Not all testing laboratories report your results in an identical manner. This is because some parts of the marker measured are regarded by some laboratories as constant and so are not counted and reported, while other laboratories count these sections.

This website uses the Ysearch nomenclature for consistency because I only show the results of people who have reported their results in a public database.
