Y-chromosome STR (Short Tandem Repeat) marker test results (Y37 &Y111) are posted in two ways: 1) at the individual tester's personal page - click on the "Results and Tools" link at the top left, then on "Y-DNA," then on "Y-STR Results" to access the results , i.e. the repeat count at each STR marker; 2) Results for all Y37 and Y111 testers in the project are displayed in a single chart accessible right here. Click on the "DNA Results" link at the left, then on "Y-DNA Results Overview" to see them. Testers are identified by kit number and have been separated into subgroups according to their SNPs and STR marker mutations.

Y-Chromosome SNP (Single Nucleotide Polymorphism) test (Big Y) test results are shown in the form of a "Block Tree" accessble on the personal page of each Big Y tested participant. Click on the "Block Tree" link to see the results in graphic format. This displays the SNPs found in the male line of descent of the tested person.. Closely related branches are also displayed in adjacent columns of the Block Tree, showing the SNP branch points and listing the tested persons in those branches. The terminal SNPs of Big Y tested participants are also displayed in the STR results chart cited above. The Group Time Tree is also a useful display of the Big Y test results for the entire projecy. This can be accessed by clicking on the "DNA Results" link at the left. 

Autosomal DNA (atDNA) test results (aka Family Finder) are posted on the tested person's personal page as a list of "matches," i.e. genetic cousins identified in the testing. The measured amount of shared atDNA, in centimorgans (cM), and the estimated degree of kinship for each match are indicated. The number of matches is usually quite large (thousands) so the search filter should be used to limit the display to manageable numbers. By entering a specific surname of interest, only genetic matches claiming that surname in their ancestry will be displayed. Autosomal DNA is what Ancestry looks at in its testing. If you have been tested at Ancestry you can upload the results at FTDNA at no cost.

Mitochondrial DNA (mtDNA) is passed from mother to daughter without change except for random, infrequent mutations. This is used for tracing direct female lines of descent but is not relevant in researching male lineages of a single family surname so is generally not used in this project.
