I highly recommend using an existing DNA service (I use FTDNA) to sequence the Y chromo and/or MTDNA of your living direct relatives (where it makes sense.. only one Y for male line, etc) because the samples are kept in storage and you can use them for sequencing later as technology drastically ramps up. My Y data is available to researchers and my and my father's MTDNA are in Genbank. Genetic anthropologists use the data to fine tune our knowledge of historical population movements. The current theory is that I am descendent from the Vistula Veneti. I just wish more people had an interest so that there were more data samples. You can't just go around demanding peoples' DNA, even if it has nothing to do with the parts that influence your health.
