Family Surname DNA Project is ready to go!!

Hi Everyone,

The DNA Surname project is finally set up. Our own web-site is not up and running yet but you can be still join now. If you go to and look under the Cosner Family Project, you will be able to request to join there. I've requested that Kastner be added to the
project name so it will be easier to find. This project will encompass all of the various spellings of Kastner such as Cosner, Costner, Castner, Casner and others.

Some of objectives we have are:

Identify others who are related
Prove or disprove theories regarding ancestors
Solve brick walls in your research
Determine a location for further research
Validate existing research

The Y chromosome is passed from father to son unchanged, except for a mutation about every 500 generations. Testing the Y chromosome will provide you with a genetic finger print consisting of 12 or 25 numbers. By comparing this finger print to others with your surname, you can determine
if they are related. This means that in order for a person to be tested, it must a male of direct lineage to the name.

Family Tree DNA recommends establishing the Project with the 12 marker Y chromosome test. 12 markers are sufficient to determine whether or not two people are related. In addition, the 12 marker Project Price of $99 is more affordable for participants, enabling you to recruit more participants.

The value of the 25 marker test 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 25 markers for a small additional fee of
$90. The objective of the upgrade to the 25 marker test is to reduce the time frame of the common ancestor between the matching participants. The common ancestor also referred to as the Most Recent Common Ancestor, or MRCA.

Typically, participants are very interested in upgrading their 12 marker test to 25 markers when a match occurs. Two individuals are considered related for the 12 marker test if they match 12/12, 11/12, and sometimes with 10/12. In the first two situations, an upgrade to the 25 marker
test is recommended.

I'm really excited about getting this project off the ground. One test has been ordered already. For this to work, we must have participants. Our web site will maintain results of those who ordered the tests as long as
they have given permission. I know that I would love to find out what the tie is to many of the families out there.

If you have questions, please contact me. If you are concerned about security and privacy, please check out

Thanks, Sandy
