Dian, My answers are from a non-professional perception, but from one who has experience with three surname DNA projects (Arnold, Webb, Burgess). 1. There is a remote possibility that an early relationship between you husband's ancestors and your own could be "suggested" by an analysis of the mitochondrial DNA for you both. I am not sure why it would matter since the dozens of marriages among unrelated lines since has either throroughly diluted or enriched your gene pool. You will find there are many people without the same surname who share the same YDNA with your sample, a mystery not easily explained. 2. The coordinator for each surname DNA project is a volunteer, usually someone descended from the same surname. The understanding and organization ability of these volunteers is highly varied. Some delve too deep into the analysis for the average participant; some have excellent biologically-aware advisers who help with the analysis; others only post the data and leave the analysis up to the participant; while others give careful attention only to the lines in which they have a special interest. However, even those who do not post much help are to be appreciated for giving the time to try to organize and answer questions related to that line. 3. There are more than a dozen organizations who do genealogically-related DNA research. Some of these are listed on Megan Smolenyak's book, Trace Your Family Roots with DNA, and on her web site _www.honoringourancestors.com_ (http://www.honoringourancestors.com) Some of these organizations have results that are compatible and can be compared, but others stand alone. You will find a world of helpful DNA information on Megan's website. 4. There are 10,000 things you have missed. This is an evolving science and like the proverbial line of passing Chinese, it is unlikely to end. You will see an excellent example of this when the real scientists respond to this note to point out what an ignoramus I am. Mel Arnold
