Hi David I have the same situation in my Mallett DNA study, and my understanding is that the "I" and the "R" groups are something like 10,000 years apart, so there is no possibility of any connection in genealogical time. For what it's worth, my "I" participants all have origins in France, whereas the English branches are mostly part of the "R" group. There are some "R" group participants from France too. Bob.

Bear in mind the possiblity of non-paternity events (NPEs) if you have reason to believe the two lines have a common pedigree on paper. -Mark Bunch (GOONS #6223) ---------------------------------------- > To: [email protected] > Date: Wed, 27 Apr 2016 05:22:25 +1200 > Subject: [G] DNA Haplogroup > From: [email protected] > > Hi, > I have a question concerning Haplogroups the questions is; > Based on tests done to-date the results show two different Haplogoups as > such, would I be correct in interpreting these results as showing two > different ancestral lines and more than likely two different origins > even though the known origin in both cases is Northern Ireland based on > research done to date? > The Haplogroups are; > I2a2 > > R1b1a1a2 > > Regards, > David J Grimshaw (or is it Grimason?) > Genealogical Researcher of the "Grimason" surname and variations of the "Grimason" surname World Wide. > A One Name study registered with the Guild of One Name Studies (GOONS): 6138 formerly 2962 > The "Sherlock Holmes" of this family according to some. >
