Our ancestry includes many descendants of Mhic Criomain - Mhic Cruimein men and women. Starting in the mid-late 1700's many people migrated to North America and Australia. While recent discoveries of genealogy documentation improve our knowledge of various family branches, it is natural to use science to help clarify various family lines.
DNA testing for our people started in 2006 and continues through a project at Family Tree DNA and also at YFULL.com.
The map to the left is the projected distribution of the male branch (YDNA) I1 haplogroup. The I1 YDNA haplogroup is one of the two main branches for the MacC' families. The other branch is R-M269.

When I started my serious genealogy research in about 2005, genetic genealogy was in its early stages. Family Tree DNA (FTDNA) was specifically established to provide DNA testing for genealogy purposes. So, in 2006, I ordered my first DNA tests.
Over the years, I have found some near cousins and assisted distant cousins in finding our most recent common ancestors. These connections have occurred on both my paternal and maternal lines.
As more people reviewed their DNA results and new company’s joined the genetic genealogy community, especially Ancestry.com, 23&Me, & YFULL.com, more matches started appearing. One of the most important improvements included FTDNA accepting results from other DNA testing companies. This provided a path to expand our comparison of DNA results.
So, we started a project at FTDNA – for both women and men. Here is the link to the project.
Examples of DNA Connections
There have been many connections based on some matching DNA results. For example, I have found paternal ties to other Scottish lines, including McLean, MacCaskill, McKenzie, & Seaton. In recent collaborations with distant cousins we have used autosomalDNA and genealogy research to locate ancestors of my 3rd great grandmother, Mary McLean (married to John McCrummen in 1804, North Carolina).
In the I1 branch, there are two sub-branches tied to MacCrimmon, McCrimmon, and McCrummen men.
The I-FGC15556 branch includes ancestors of living men from Isle of Man, Norway, North America, and Scotland. Importantly, There are two samples from ANCIENT men who lived in Greenland and Norway (designated as VK in the I-FGC15556 subbranch on this page).
Based on the genealogy and history developed by Clan MacCrimmon Society, this is the branch tied to the Hereditary Pipers of the Chiefs of MacLeod of MacLeod.
The I-Z73 includes men currently living in Texas, Alaska, Washington, and Scotland. Almost all of the YDNA tested men in this branch indicates the publicly posted results are Nordic and northern Europe origins.
In the R-M269 branch, the YDNA tests are limited so the sub-branch locations of the MacCrimmon men are not currently known. The few MacCrimmon men who are reported in the branch currently live in southern Ontario and Alberta. For at least one group of these men have documented origins to MacCrimmon men migrating to North America from Glenelg, Scotland.

In particular she has an excellent summary on DNA, including yDNA (male), mtDNA (mitochondrial), and atDNA (autosomal):
Founded in 2005, The International Society of Genetic Genealogy (ISOGG) has extensive information on its site. “The mission of the International Society of Genetic Genealogy is to advocate for and educate about the use of genetics as a tool for genealogical research, and promote a supportive network for genetic genealogists.” http://isogg.org
