I have had DNA testing on myself and family members. I think the autosomal testing is very useful. You will find cousin connections. Some are very hard to trace via paper trails, but others show obvious connections or at least they narrow down possible common ancestry. I have found it very helpful, and I am looking forward to breaking down brick walls as more and more matches show up. Once I see common ancestors for several matches, I can pursue a common, as yet unknown ancestor. The patrilineal and matrilineal testing are very interesting but each is respectively limited only to the father's father's father (etc. ad infinitum) and likewise the mother's mother's mother's mother (ad infinitum) without allowing for any of the names married into the lines to be shown at all. So it is interesting, but very limited in what it can tell you about your ancestry. I highly recommend autosomal testing, and I also blog about it. Susan
