1. Y-DNA Test: The Y-DNA test kit is best for tracking your paternal line or the blood line from your father and his father back through the earliest generations of your family. The results of Y-DNA testing are stated as probabilities along a continuum of time where the member’s earliest paternal ancestor may be found. Clan Henderson Y-DNA study uses the results of this test to group members into family groups so individual members assigned to each group can work together to confirm and expand their paper-based research knowledge.
There are three standard levels of Y testing available.
- Y-DNA37: This test includes a panel of thirty-seven Y-DNA STR markers, those from the Y-DNA25 test and plus twelve more. This is the recommended test to trace the paternal ancestry of males for genealogical purposes. The additional markers refine the predicted time period in which two individuals are related and eliminate unrelated matches. A perfect match at thirty-seven markers indicates the two individuals share common ancestry in recent times.
- Y-DNA67: This test includes a panel of sixty-seven Y-DNA STR markers, those from the Y-DNA37 plus thirty more. The additional markers refine the predicted time period in which two individuals are related and eliminate unrelated matches. A perfect match at sixty-seven markers indicates a common ancestor in recent generations. This is the ideal test for matching if a break in the paper trail, such as an adoption, is known or suspected.
- Y-DNA111: This test includes a panel of sixty-seven Y-DNA STR markers, those from the Y-DNA67 plus forty-four more. The additional markers refine the predicted time period in which two individuals are related. They 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
2: mt-DNA Test: The mt-DNA test kit is best for tracking your maternal line or the blood line from your mother and her mother through the earliest generations of your maternal family. The results of mt-DNA testing are stated as probabilities along a continuum of time where the member’s earliest maternal ancestor may be found. 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.
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.
3. The Family Finder Test: The Family Finder kit 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 result yields a calculation of a matching relationship based on shared segments of DNA. Any two people within a common population may share some DNA. However, as matching segments of DNA become longer with more matching segments, it is likely the two donors share a recent common ancestor. Family Finder results include the names of matching members as well as various surnames that commonly hold the same matching segments. There is a growing trend among genealogist to combine autosomal testing in combination with Y-DNA and mt-DNA testing.
4. Autosomal Transfer: Members who previously tested with the DNA service known as 23andMe and Ancestry.com may transfer their results to the Henderson DNA Project without charge. 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.
