iCARA irish caribbean ancestry - reconnecting through dna
What to expect from your results If you take a Y-DNA test, there are several possible results that you could get, including unexpected results. Before testing, you should go through each possible result on the list below and ask yourself "how would I feel if I got this result?". If you feel you could accept each result, only then should you take the test. Having read these possible outcomes, if you are still happy to go ahead and have the DNA test, please click here to join the project and pay for your own test, or click here to see if your surname qualifies for sponsorship.

Here is a list of the possible results - it is not comprehensive but it will give you an idea of what to expect.
There are certain genetic signatures (or haplotypes) that occur more frequently in present-day Ireland than anywhere else in the world. Whilst this is not conclusive evidence of an Irish connection it is highly suggestive of one. Put another way, the chances that your Y-DNA came from somewhere else may be very remote indeed. The science of ancient migrations and population genetics is making huge strides at the moment and the next few years will probably see major scientific breakthroughs in this area.
With every project, there is always the chance of an NPE or Non-Paternity Event. This simply means that the transmission of Y-DNA down the direct male line (from father to son) has been interrupted at some stage. There are many possible causes for this including adoption, children adopting their mothers name, sharing out children to be raised by relatives, births out of wedlock, legal name changes, and ancestors taking on the surnames of the plantation owner. If your genetic signature is more likely to be African, this could indicate that there was an NPE somewhere along your line, or that your Irish surname was bestowed upon your ancestors by a plantation owner. AnAfrican genetic signature suggests that your Y-DNA has been passed down from someone who lived in Africa within the last several thousand years, rather than in Europe or elsewhere. This will take you on a whole new journey back to Africa and the Project Administrator will guide you to projects that will help you continue this journey.
An Asian genetic signature suggests that your Y-DNA may have been passed to you from the Native Indians of the Caribbean (such as the Caribs or Arawaks).
According to admixture tests, the average African American is 65-80% sub-Saharan African, 19-29% European and 0.6-2% Native American. In many cases the presence of European DNA is likely to reflect the widespread sexual exploitation of women during slavery and forced breeding with white men. This is supported by the fact that when we look at Y-DNA in particular (on the direct male line), 35% of African American men have European Y-DNA. Interestingly, 3-4% of "white" people have been found to have "hidden" African ancestry (including myself). There are various projects that will help you explore where your European DNA came from.
Many of the genetic signatures or haplogroups found in Ireland are also quite common in the UK and continental Europe, so it may be necessary to do further testing to see if it is possible to refine your haplogroup even further (i.e. further testing might identify your signature as being more likely to be specific to Ireland). This is an evolving science and the next few years will see major leaps forward in determining ancestral migrations within Ireland, Britain, and Europe.
You may have a very rare genetic signature that doesn't match anyone because no one else with the same signature has taken the test. An example of this happened in 2012 when the Y-DNA results of an African American man rewrote the genetic history books.
This is a common finding for all DNA testing participants. It could simply mean that not enough people with your particular surname have been tested. Nevertheless, it may still be possible to draw some useful conclusions from your results. If many of your matches have Irish surnames, these could be descendants from a common ancestor to you all who did indeed live in Ireland, but PRIOR to the introduction of surnames (i.e. more than 1000 years ago). This information can be used to help pinpoint or confirm the location of your Clan Homeland, using the methodology developed by Dr Tyrone Bowes of IrishOrigenes, who can prepare a personalised report for you if you wish. In addition, it may be possible to make contact with local communities near the Clan Homeland and encourage them to test local people with your surname.
This probably means that you and your match shared a common ancestor within the last 1000 years. The closer the match, the more likely that you and your match are recent genetic cousins. The next step is to make contact and to try to establish if there is any family lore or even documentary evidence of family members going to the Caribbean. This collaboration may lead to important discoveries about the local history on both the Caribbean and Irish sides.
What to expect from your results
If you take a Y-DNA test, there are several possible results that you could get, including unexpected results. Before testing, you should go through each possible result on the list below and ask yourself "how would I feel if I got this result?". If you feel you could accept each result, only then should you take the test.One important thing to remember is that if you have been passed down an Irish surname by your ancestors, and you identify as "being Irish" as a result, then you ARE Irish, no matter what the DNA test results say (or anyone else for that matter). YOU determine your own identity, not a DNA test.
