Y-DNA Test

The Y-DNA test kit is best for tracking your paternal line from your father and his father back through the earliest generations of your family.  Clan Henderson Y-DNA study uses the results of this test to group members into family groups having a common male ancestor in the past 500 years. Individual members in each group can work together to confirm and expand their paper-based research knowledge. The Y-DNA test allows one to determine the probability that another person shares a common male ancestor in the past and to estimate how far in the past that connection lies.

There are three standard levels of Y testing available.

Y-DNA37: This test includes thirty-seven Y-DNA Short Tandem Repeat (STR) markers. This is the lowest number of markers we recommend testing. Testing fewer markers leads to many false genealogical leads.  A perfect match at thirty-seven markers indicates the two individuals share common ancestry in recent times but even a perfect match at Y-DNA 37 does not guarantee a genealogically relevant match.

Y-DNA67: This test includes thirty markers in addition to the Y-DNA37. The Y-DNA67 test contains enough markers to provide high probability that DNA matches are genealogically relevant and to eliminate unrelated matches. A perfect match at sixty-seven markers indicates a common ancestor in recent generations. This test is also useful where a break in the paper trail, such as an adoption, is known or suspected.

Y-DNA111: This test includes forty-four markers in addition to the Y-DNA67. The additional markers should completely eliminate unrelated matches. A close match at 111 markers indicates a common ancestor in recent generations, and an exact match indicates a close or immediate relationship.

mt-DNA Test:

The mt-DNA test kit allows tracking your maternal line from your mother and her mother through the earliest generations of your maternal family.  The slow rate of mutation of the mt-DNA makes this test most useful for understanding the ancestral origins of your maternal line. These results are displayed on the Clan Henderson FTDNA website so individual members can view other results on file that closely match their own.  When a match is discovered, the members can work together to confirm and expand their knowledge. Note that even an exact match to the Full Genomic Sequence may not provide information that is genealogically useful.

There are three standard levels of mt-DNA testing available.

mtDNA (HVR1): The HVR1 test shows basic maternal ancestry reaching back hundreds of thousands of years. It includes testing to determine your basic haplogroup placement.

mtDNAPlus (HVR1&2): The HVR1&2 test is also able to provide more refined geographic origins data for your maternal line in the last 2,000 years.

mtDNA Full Genomic Sequence: The mtDNA Full Sequence test is the preferred test for understanding the genealogy, historic, and ancient ancestry of your direct maternal line. By testing the full mitochondrial genome, you will be placed in one of hundreds of mtDNA haplogroup subclades according to current published peer reviewed literature. Each subclade has a unique migration history that traces from ancient times through more recent historic events.

The Family Finder Test

The Family Finder test compares your autosomal DNA to that of other people in the FTDNA database who have taken the Family Finder test or another autosomal test transferred to FTDNA. The results can also be exported to the gedmatch.com site to compare with results from other test companies. The results are useful for identifying cousins related within the last six generations, and calculating the probable number of generations in the past your common ancestor lies. The more recent the common ancestor of the two donors, longer the matching segments will be.  Family Finder results include the names and contact information of matching members, their list of ancestral surnames, and the probable number of generations to a common ancestor.  There is a growing trend among genealogist to combine autosomal testing with Y-DNA and mt-DNA testing.

Autosomal Transfer

Members who previously tested with the DNA services 23andMe and Ancestry.com may transfer their results to the Henderson DNA Project.  Those who tested with any other DNA service, other than FTDNA, 23andMe or Ancestry, may also be able to transfer their findings to the Henderson project but this is on a case by case basis and will incur a charge.  Not all test results from other DNA services are compatible with Family Tree DNA.

To get personal assistance with DNA or Genealogy related issues, contact the Clan Henderson Society DNA and Genealogy Coordinator. She can answer simple questions and suggest one of over 30 volunteers who might provide assistance. Note: this is a free service, managed by volunteers. First, priority is given to members of the Society. Second, we ask that you have patience--we are not a "for profit" company.
