I used familytree dna to test my uncle for both his male line and his mother's line.  Company is in Houston, Tx.  Have been very satisfied with their service.  They do give you info on 15,000 + years ago as well as 1 to 4 generations.  They do say that my grandfather's and grandmother's female line came directly from Africa,  They further tell you that the dna (male) line has a high incident of coming from the Great Britain area and the mtdan (female) line has a high concentration of that mtdna in the Scandinavia and Germany area.  In other word, my grandmother was a Viking before the female line migrated to Germany.  I do know that my grandfather's line was either from England or Scotland before immigrating to US  My Grandmother's mother was born in Germany.  The other thing I like about their service is that they have free projects you can join.  Projects can be on surname, country or county of origin, etc.  Very educational.  The projects track all members dna and mtdna and you can see how they compare to each other.
