Description

In 1997 a team of inquisitive Anthropologists and M.D.'s from America, England and Israel tested a theory to determine if men who shared an oral tradition of being Cohanim were in fact related. They discovered that when using a series of markers on the male inherited Y-Chromosome they would see a pattern that was similar or identical between a large percentage of these men who claimed an oral tradition of being Cohanim, regardless of last name. This was found to be the case for men of Ashkenazi and Sephardic ancestry and has also been found among men from Jews in Yemen...all who matched each other on the Y chromosome and all who share the same oral tradition of being Cohanim.

This project is for any male Cohen and variants worldwide, Ashkenazim, Sephardim and Mizrachi gladly accepted!. People with the name Cohen, Kogan, Kagan, or derivative, or with a family tradition of being a Cohen have shown an occurrence of the Cohanim sequence up to 50-60 percent of men tested. The project examines presence of a Cohanim marker as well as checks close familial relationships.

It is now possible to test yourself against the original 1997 study using the Family Tree DNA standard 12 marker test. If you have the same Cohanim marker values and your results match the prior study you'll find on your results page a picture of the symbol of the Cohanim and more info about that original study.

Requirements

A Surname Project traces members of a family that share a common surname. Since surnames are passed down from father to son like the Y-chromosome, this test is for males taking a Y-DNA test. Females do not carry their father's Y-DNA and acquire a new surname by way of marriage, so the tested individual must be a male that wants to check his direct paternal line (father's father's father's...) with a Y-DNA12, Y-DNA37, or Y-DNA67 marker test. Females who would like to check their direct paternal line can have a male relative with this surname order a Y-DNA test. Females can also order an mtDNA test for themselves such as the mtDNA or the mtDNAPlus test and participate in an mtDNA project.

MALE LINE TESTING - FOR GENEALOGY AND ANTHROPOLOGY
Y-DNA12
More info...
Order Now

This is a male specific test. Results identify the ethnic and geographic origin of the paternal line. It includes a balanced panel of twelve Y-chromosome Short Tandem Repeat, STR, markers. Additional markers refine the predicted time period in which two individuals are related. It is used to affirm or disprove a genealogical connection on the direct paternal line. A haplogroup is determined and backed by our SNP Assurance Program. When another person shows identical results within our database, if both parties have signed the Family Tree DNA Release Form, then we will inform them of the match. The customer will also receive a certificate and report describing the testing process and the meaning of twelve marker matches.

Y-DNA25

This is a male specific test. It includes a balanced panel of twenty-five Y-chromosome Short Tandem Repeat, STR, markers. The additional markers refine the predicted time period in which two individuals are related. It is used to affirm or disprove a genealogical connection on the direct paternal line. A haplogroup is determined and backed by our SNP Assurance Program. When another person shows identical results within our database, if both parties have signed the Family Tree DNA Release Form, then we will inform them of the match. The customer will also receive a certificate and report describing the testing process and the meaning of twenty-five marker matches.

Y-DNA37

This is a male specific test. Results identify the ethnic and geographic origin of the paternal line. It includes a balanced panel of thirty-seven Y-chromosome Short Tandem Repeat, STR, markers. This is the recommended test to trace the paternal ancestry of males for genealogy 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. A haplogroup is determined and backed by our SNP Assurance Program. When another person shows identical results within our database, if both parties have signed the Family Tree DNA Release Form, then we will inform them of the match. The customer will also receive a certificate and report describing the testing process and the meaning of thirty-seven marker matches.

Y-DNA67

This is a male specific test. Results identify the ethnic and geographic origin of the paternal line. It includes a balanced panel of sixty-seven Y-chromosome Short Tandem Repeat, STR, markers. 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 very recent times. This is the ideal test for matching if a break in the paper trail, such as an adoption, is known or suspected. A haplogroup is determined and backed by our SNP Assurance Program. When another person shows identical results within our database, if both parties have signed the Family Tree DNA Release Form, then we will inform them of the match. The customer will also receive a certificate and report describing the testing process and the meaning of sixty-seven marker matches.

FEMALE LINE TESTING - FOR GENEALOGY AND ANTHROPOLOGY
mtDNA

Both men and women may take this test. It traces the direct maternal line without influence from other lines. This test is for HVR1(16001-16569) of the mitochondrial DNA. A panel of twenty-two SNPs is included for backbone haplogroup placement. Results identify the ethnic and geographic origin of the maternal line. The customer receives a certificate and report generally describing the testing process and the meaning of matches. Results are placed in our database. When another person shows identical results, if both parties have signed the Family Tree DNA Release Form then we will inform them of the match.

Both men and women may take this test. It traces the direct maternal line without influence from other lines. This test is for HVR1(16001-16569) and HVR2(00001-00574) of the mitochondrial DNA. The addition of HVR2 to results reduces the number of matches. A panel of twenty-two SNPs is included for backbone haplogroup placement. Results identify the ethnic and geographic origin of the maternal line. The customer receives a certificate and report generally describing the testing process and the meaning of high resolution matches. Results are placed in our database. When another person shows identical results, if both parties have signed the Family Tree DNA Release Form then we will inform them of the match.

Both men and women may take this test. It traces the direct maternal line without influence from other lines. This test is for all three regions of the mitochondrial DNA: HVR1(16001-16569), HVR2(00001-00574), and the coding region (00575-16000). The entire mitochondrial genome is tested and this is the last mtDNA test that a person would need to take. A perfect match indicates a common ancestor in recent times. Results identify the ethnic and geographic origin of the maternal line. The customer receives a certificate and report generally describing the testing process and the meaning of matches. Results are placed in our database. When another person shows identical results, if both parties have signed the Family Tree DNA Release Form then we will inform them of the match.
