Jarman German Jermyn etc DNA Project

Dear Jarman / German / Jermyn researchers,

I am happy to announce the launching of a DNA study for genealogical purposes to supplement our research into our Jarman, Jarmon, German, Jerman, Jermyn (and other variant spellings) ancestors. A new web page for this project is now available at http://www.inct.net/~german/dna.htm

Rather than linking all Jarmans (and variants) back to a single common ancestor, our surname appears to have multiple origins. Although we share the same surname we do not seem to all share the same common ancestor. Modern surname distribution studies reveal that no single concentration of Jarman, and variants, can be found in Great Britain; the name is well represented across England and in Wales. Add to this the migrations of our ancestors both within Britain and across the seas. In colonial America, no less than five disconnected Jarman families are found in Maryland and Virginia. More are found in Pennsylvania. It is little wonder most of us at some point have lost or will soon lose the traditional paper trail that we need to lead us to our roots.

Happily, we have within each of us a biological record that scientists are learning to read - our own DNA. Genetic genealogy can already verify relationships between individuals. For example, if two men sharing the same last name believe that they are related (i.e. they have a common ancestor from whom they inherited their last name), but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers on the Y-chromosome. Fathers pass their Y-chromosomes, or “DNA fingerprints,” down to their sons with little—if any—variation, from generation to generation. And so, men with identical, or near identical DNA fingerprints (some minor variation can occur), are genetically proven to descend from a common male ancestor.

Therefore, men with the Jarman surname, or one of its several variants, are invited to participate in our own DNA testing project. If you are female, perhaps you have a father, a brother, a brother of the father, or a male first cousin from the father's brother, who will provide his DNA. Ideally, by collecting the DNA of a large sample of Jarmans, Germans, etc. we will discover several of these fingerprints and also an introduction to cousins and clues to lead us back to the paper trails we've lost. The objective of the Jarman / German DNA Project is to match up individuals or families who
share a common male ancestor of the Jarman, or variant, spelling, in North America, Australia, England, Wales, and elsewhere. But since Jarman has suspected multiple origins, the proving of the negative can also be beneficial as it helps us isolate and identify the DNA fingerprints of our particular ancestor, and it directs us away from paths that will only waste our resources.

Y-chromosome testing involves the painless use of a swab to collect a small amount of cells containing DNA from inside a person's cheek. No needles! The testing laboratory will be Family Tree DNA of Houston, Texas. Our goal is to have available a growing database of Jarman / German DNA supported lineages to aid in genealogical research for years to come. To learn more about this study please visit the Jarman / German DNA Project web page at http://www.inct.net/~german/dna.htm

I hope you are interested!
