Introduction to Genetic Genealogy Testing
(that is, DNA Testing as a tool to help with your genealogical research)
Decide on the type of testing that you can or should perform.
Autosomal SNP tests (FamilyFinder at FTDNA and simply included at 23andMe) can be used by ANYONE to possibly find ANY OTHER relative tested if you both share ANY ancestor within 6 or so generations. That is, if you have a common 5xGreat or more recent Grandparent. While we cannot support finding matches in our project directly, company testing sites provide support for matching those tested with that company. And GEDMatch is a third party site that allows you to upload your results and compare to others who have uploaded; possible finding more matches across company testing lines. Positive results are very likely if within 6 generations. After that, actual relatives may still not show a match as the "norm" for fourth cousins is just above the noise level of the general population, for most people.
Autosomal SNP tests are commonly used to determine the percentage makeup of your ancestry from different regions. This is done by identifying certain, more unique gene variations with populations or regions. As it looks across 44 chromosomes, there is more variety and mix of your recent background than with Y-DNA or mtDNA SNP. The accuracy of such regional background history is getting better every year but still the subject of much debate.
Note: Project experience tells us that the transfer of Autosomal SNP results from 23andMe to FTDNA is not worth the money. FTDNA has a much smaller user sample base in their FamilyFinder product to compare against and a much smaller SNP marker set; overall this makes their percentage comparisons less succesful. And the import throws out 23andMe's Y, mtDNA, and X SNP marker results. Although 23andMe has a far greater number of testers (appears to be 10-20x more), testers are using their product more predominantly for health analysis and not genealogy. So although you may find matches there, responces to inquiries for collaboration on genealogy is sporadic. For best results, do autosomal testing directly at both companies. Our experience shows 23andMe's Haplogroup analysis to be much more believable.
yDNA STR testing can be used by males to test if they are related in their male-only ancestor line to others similarly tested. It works for upwards of 1,000 years (30 generations) and is not limited to the 6 or less generations of Autosomal SNP. For most of western Europe (except Spanish-derived cultures), the male-only line will follow the surname inheritence and hence the origination of Surname DNA projects like this one. This is the main test you need to perform to really be a part of this project. But it can only be done by those that are a male descendant all the way down the line. The yDNA STR test is somewhat unique to FTDNA. Order a yDNA STR test in the Hoar / Hoare / Hore Surname DNA Project and become a member at FTDNA. Already tested at FTDNA? Simply join the Project. Were you yDNA STR tested at another company? Transfer your results to FTDNA to join this project. yDNA STR testing is by far the largest component of FTDNA's user base. A 12 marker test is useful to initially see if you are in the ballpark with a surname project. A 37 marker test is really a minimum to verify you are in a surname family. More than 37 markers help determine branches in a family. You can start with 12 and upgrade later. No additional cost for testing incrementally; just additional time to reach your full results. We suspect, they do the full test initially, no matter what you pay for, and simply provide access to the additional levels of results as you upgrade.
yDNA SNP and mtDNA SNP testing can be used to find your early human ancestry. Often termed Population Studies or Haplogroup understanding. Like for yDNA STR, yDNA SNP only tracks your male or paternal line. mtDNA SNP tracks your female-only or maternal ancestry as the Mitochondrial DNA is only passed down in the egg. The Y-Chromosome is inherited by males from their father. The mtDNA strand inherited by everyone from their mother. SNP markers more rarely change and are more commonly shared among many people and so are not useful for nearer-term genealogy and surname work.
- yDNA SNP testing can help with the yDNA STR surname project by confirming your grouping. Those with very similar yDNA STR results should have identical Haplogroups as determined by their yDNA SNP results. STR results can sometimes predict, but not determine, the testers Haplogroup.
- mtDNA strands are very short (only about 16.000 base nucleotides) with very few SNP's. Thus it is very common to have common mtDNA test results but have absolutely no relation in genealogical time to each other (i.e. less than 1,000 years).
- Because SNP's are often stable for thousands of years, those with common SNP test results may not be related in any genealogically determined time frame. Because SNP's do randomly change though, deep SNP studies in surname projects identify changes that have occurred within the last 500 years. Infrequent changes do not mean they cannot change in the near term. The once every 1,000 or 5,000 year change could have occurred in the last generation. Identifying these private SNP changes can sometimes help determine family lines in surname group just as STR changes can.
- Instead of individual SNP tests at FTDNA, project admins recommend testing with 23andMe or the National Geographic Genographic Project. With the latter, you can import your results into FTDNA as they have helped develop the project. But there are far fewer SNP's tested than with 23andMe. FTDNA only supports importing autosomal SNP results and not yDNA nor mtDNA SNP results.
Project leaders have spreadsheets and other support material to extract your ISOGG nomenclature SNP results from your downloaded 23andMe test data and map it into other versions of the ISOGG Y-DNA Haplogroup tree. Either into the 2010 tree FTDNA uses (so you can do apples-to-apples comparisons there) or into the latest 2014 tree available to understand the latest terminal SNP's used in this Surname DNA project to identify their subgroups. This avoids a need to do the one, many or all individual SNP marker tests with FTDNA. Report your SNP results informally to project admins and they will make notes attached to your account that they can see to help them in placing you into the right subgroup. The Haplogroup tree for mtDNA is at PhyloTree but no tools to map into the latest one are available.
Work with the project admins to map your results into the subgroups already identified or let them help take everything you have and figure out if there are any new avenues of genealogical research for you going forward. One of the project admins was stumped twice. Another admin helped them get past the name change around 1900 that was a complete surprise. And the DNA testing helped find the second name change at the 6th generation in 1800 by linking him to a 12th generation ancestor. Working forward from that ancestor drastically narrowed the search space to find the stumped 1800 link. So check out our pages and see if our collected genealogical research and DNA results might help you.
