There are three different types of tests that your brother could have done. Which are you considering?

The Y-chromosome test gives you lineage of ONE male in each generation, NONE of the females. It doesn't matter which brother you test. All should have the same Y-chromosome which will give you your WEST male lineage.

2. The mitochondrial (mtDNA) test gives you the lineage of ONE female in each generation, NONE of the males. But this would be the lineage of your mother, and her mother, etc.

With these two tests, the DNA submitted is compared to a database of samples from around the world, and you will be given the name of the ethnic group which matches yours. Or if they can't match it they will tell you that.

Very dark skinned people CAN have a European Y-chromosome (about 1/3 of African American males tested do) or European mtDNA result (about 2% of African Americans do). Skin color won't predict what shows up.

There is a third type of test which gives you percentages of four ethnicities that you may be: (1) European (2) Native American (3) Sub-Saharan African (4) East Asian. This test will not connect you to any specific ethnic group.

Are you considering testing the females? Do you have aunts on the WEST side? Testing them will give you the results for your WEST Grandmother's maternal lineage. Testing one of your mother's brothers (if there are any) or their sons can give you your maternal grandfather's lineage.

Here is the web site for African Ancestry, one of the companies I have used: http://www.africanancestry.com You can order the test online. Costs, procedure are spelled out there as well.

They do both the Y-chromosome test (males only) and the mitochondrial test (males and females).

I've also used http://www.ancestrybydna.com and http://www.tracegenetics.com

>I have white West ancestors in my family. Should we do the Slaveowner >West side first?

Since you are testing your family, I'm not sure I understand this question. Do you know who the slaveowner was? If so, do you have contact with descendants of that slaveowner? If not, there is no way to do the slaveowner West side.
