The public service chanel here in Everett, Chanel 9 has a show on the 
genealogy search for Blacks to find thier genetic makeup. Since I have 
traced 3 Mulato lines in 3 different states, Jalisco, Zacatecas and 
Michoacan  I was very interested in what they had to say.  They shared 
the fact that the Portuguese controlled the slave trade and that in 
the time frame I'm looking at, mid 1600's the odds are the slaves were 
from Angola. They shared the major advancments they are making daily 
in genetic testing now being able to isolate genes to find what 
percentages we are of different ethnic backgrounds.  I find this all 
very exciting and hope if you get the chance that you will get to 
watch this very informative show. Even if you have no black ancestors 
the sharing of genetic information and genealogy research methods is 
great and well worth watching.
