  •  Europeans have the privilege (16+ / 0-)

    of coming from a place that for the most part has excellent written records, and people can trace their kinship back a long ways.

    People in the African diaspora don't have that for the most part. Some of us have been lucky enough to find the slave progenitor who was stolen, and where they were stolen from, but not all.

    That is the source of disappointment. It'd be nice to find an ethnic group in Africa. As of this moment I don't exactly have that. Indirectly I've found some, but only indirectly.

    •  Why be disappointed? (7+ / 0-)

      Genetic testing is a powerful tool which has just barely been tapped as a historical, archaeological and genealogical aid.

      As DNA testing becomes cheaper, I'm sure that there will be a lot more genetic testing of different African populations.

      While the combination of European trade and colonialism moved some African groups around and destroyed others, there are likely lots of tribal and family lineages still out there waiting to be discovered.

      Likewise, as genetic testing becomes more common, more lineages will be revealed within the African American community.

      In time, you might be able to say with certainty that you are descended from a particular tribe or clan in Africa, or that you have third cousins you never knew about living in another state. You might not have your ancestors' names before 1870, but your DNA will help reveal your extended family.

      which most immigrant to the US were not, there are unlikely to be records going back in Europe much further than the 1850s.  For me, that's only my great grandparents.

      Wars, fires, floods, pogroms, and genocides have destroyed many Europeans' history as well.

    •  And even if your Y chromosome came (4+ / 0-)

      From an ethnic group that could be identified,  that doesn't really tell you much about the rest of your genome.

      Each gene has its own family tree,  and they're often totally unrelated. There are probably genes in my genome whose common ancestor with their counterparts in yours predate the existence of mammals.

      This stuff is fascinating,  but personalizing it can lead to error.
