FAQ

Q: My 4th great-grandfather is Denis Driscol born 1745 in Ireland. As I am female, could one of my sons do the DNA test?
A: No, the surname testing is based on the "Y" chromosome which is a paternal test and thus all samples must be derived from a male surnamed DRISCOLL or a variant thereof.

Q: My husband's mother's mother's mother is a DRISCOLL. Would he be able to participate in the DNA research?
A: It depends on your research objective. If it is directed at Mrs. Driscoll, yes as per details, otherwise no.

Q: What paternal test should I order?
A: The 37 marker test is the most cost effective. An upgrade to the 67 markers is useful to improve the confidence levels in any conclusions drawn.

Q: How is the DNA collected?
A: Its done at home by simply swabing the inside of the cheek. Family Tree DNA will mail you a collection kit and it comes with instructions on how to swab the inside of the cheek and mail it back.

Q: How long does it take to get results?
A: Six to eight weeks.

Q: If we realize a paternal match, how far in back in time does this mean we have a common ancestor?
A: For two individuals who match perfectly a 37 marker test gives you the following range: within 3 generations (50%) likelihood and within 7 generations (95%) likelihood. With 67 markers one can get to 2 and 5 respectively.

Q: How long is a generation assumed to be?
A: It seems most researchers are using 30 and 25 years per generation for yDNA and mtDNA respectively.

Q: What is a Haplogroup?
A: Research to date has not identifed the most ancient of our ancestors as having originated from several different groups. Your Haplotype is that set of numbers which defines your DNA and your Haplogroup characterizes your most ancient ancestor. In a sense your Haplogroup is DNA's "brick wall" in your link to Adam or Eve.

Q: If we all come from Adam and Eve then don't men in turn all have the same Y-chromosome?
A: Mutations occur resulting in different lines. In fact one complication in interpreting results is that mutations can occur causing once different lines to evolve with the same Y-chromosome and effect termed 'convergence'.

Q: How can I be sure that an act of infidelity or adoption has no occured in the line between me and my most ancient paternal ancestor?
A: Convince your most distant relation sharing that ancestor to submit a DNA sample. You have to find someone who shares only that ancestor with you. If you both match then you will be sure.

Q: Should I be concerned about privacy?
A: No. The DNA testing being done has no forensic or medical value. It will not reveal any genetic defects, diseases or uniquely identify you as an individual. You may wish to review the vendor's policy statement.

Q: Please cite some examples of succesful projects as case studies.
A: Certainly! One of the best examples is: "Who Was Harvey Kelley?". In the 1990 US Census the names DRISCOLL and O'DRISCOLL rank 1569 and 17,214 respectively. The names amount to 0.009% of the population. The surnames BRANTLEY and FARR also amount to 0.009% of the population thus their projects represent reasonable benchmarks by which we can measure ours.

Q: When I order the 37 marker test on the order site, whose information do I put in the box....the person being tested...or myself..the one paying for the test?
A: Put the name of the person being tested (and let me know his name) but use your EMAIL address.
