Persons interested in participating in this project should contact
John Marsh, the project administrator, at :
John has opened up a Web site which can be accessed at: http://marshdna.arrrg.org/
This site contains a lot of Marsh information of general interest to all Marsh researchers and is well worth a visit, even if you are not interested in DNA testing.
Please note that other Marsh DNA projects may exist or be initiated within other organizations such as Relative Genetics.
A participant can opt for a test based on 12 or more markers. Generally, 12 markers are sufficient to determine whether two people are related or not.
The value of a test using more markers occurs when two participants are related based on the 12-marker test. When participants match in the 12-marker test, the test can be upgraded to additional markers for an additional fee. The objective of the upgrade is to reduce the time frame of the common ancestor between the matching participants. The common ancestor is also referred to as the Most Recent Common Ancestor, or MRCA. Two individuals are considered related for the 12-marker test if they match 12 of 12 markers or 11 of 12 markers, and sometimes with 10 of 12 markers. In the first two situations, an upgrade is recommended.
While participants may initially opt for the 12-marker test, from my
observations and experiences it is advisable to opt for the most markers
one can afford . In addition to the more detailed results obtainable it
is the most economical route.

SMGF do not charge for an analysis. However, they do not advise participants of their results. They do post the results to their database with a partial pedigree as provided by the donor - the pedigree does not include living persons. From this pedigree it is possible to learn one's results.
Once you receive your results you can then enter them to search for matches in a number of databases. Some databases available are as follows:
SMGF database - http://www.smgf.org/
Y-Base hosted by HeritageDNA - http://www.ybase.org/
Y-Search hosted by Family Tree DNA - http://www.ysearch.org/
Y-STR Database hosted by Humboldt Universitat zu Berlin - http:///www.ystr.org/index_gr.html
