Clan MacInnes DNA Project

    The Clan MacInnes YDNA Project  


Clan MacInnes has established a DNA Project for all Clan MacInnes surname variations. We are currently focusing on the male lines as these are the more definitive tests. Anyone can get their DNA tested and compared to other MacInnes members.  Jackie McInnis, our clan genealogist, has now become actively involved in looking at the data.  We also have a Clan Genealogist with over 25,000 names electronically filed.

Consider joining the YDNA project, Clan MacInnes gets substantial discounts.  Also send in your family tree so we can collect a large database of MacInnes names.  The more information we have makes the database much more valuable.


The human DNA has 23 paired chromosomes, 22 pairs of information chromosomes and one sex chromosome.  This full 23 paired set is called a genome.  Each parent passes an X sex chomosome for the female and an X or Y sex chromosome from the male which will determine the sex of the child. The DNA is passed from male to male directly with the Y-chromosome which only males possess.  Inside this chromosome are specific areas called locus, or loci for multiple locations.  At each one of these patterns is a repeating structure called an allele.  The DNA test counts these markers through what is called the Short Tandem Repeat (STR).  So when you order a 12-marker test, which defaults to using the STR, the researchers count each site (locus) and determine the repeat number (allele).  There is another test called the Single Nucleotide Polymorphisms (SNP) test that can be used to determine the haplogroup.  More information is below on the haplogroups.

Over time the allele can mutate.  The longer the time, the more probable a mutation has occurred and the allele count varies from species to species.  So the closer one matches with another, the probability increases that the common ancestor is more recent.

DNA is all a statistical game.  Humans first descended from certain areas (supposedly we all descended from a single pair, like the biblical Adam and Eve).    Certain patterns emerge from each line from the 12 marker test.  This line is called a haplogroup.  So people that have a Celtic or Viking background, like MacInnes, have a specific haplogroup.  Within each haplogroup are sub categories called subclaves  There are two main groups for most people of Scottish descent.  The R1a group is considered the Viking branch, actually the subclave R1a1.  This group is often found in Eastern Europe.  The other main group is the R1b group, or Celtic branch.  This group is found most often in Western Europe.  We have MacInnes from both R1a and R1b categories, with the Celtic R1b being the most prevalent.

This DNA information can be used in one of several ways that almost always supplement the physical genealogy trees that have been discovered from the family information.  DNA cannot detail family relationships, just ancestry relationships and origins. The marker matches of different people can be used to discover or confirm family members as being related.  This would cover more recent generations.  Usually the surnames are the same or very similar.  However this information does not cover adoptions or other ways where members may not match.

The other DNA use is called deep ancestry or roots origination.  Many members do not have strong matches, but can use the information to see what regions they are from, if they are Celtic or Viking based, and other general information.  There are also extra tests to help determine the haplogroup and subclave.

The 12 marker test does not tell very much information, some of the MacInnes DNA project members have close to a 1000 12 marker exact matches.  The only test that gives recent generation information is the 25 marker test.  The 37 test will reveal more, and the highest marker test is the 67.  Even if you are not an exact match at the 25 or 37, the 67 marker can start to eliminate certain people and advance the dates of a common ancestor.  So if you can afford it, go for the higher number.  Once the sample is sent in, you can upgrade to a higher marker level at any time.
