Sue, I think I understand your question. Your grandmother's maiden name is Reeves. She is your closest direct Reeves relative. I believe you wanted to know if there is any chance of getting a match by testing a female. The answer is none (not any chance at all). That is because women cannot have this test performed. We are testing the DNA sequence of the Y chromosome because it is the only chromosome that is passed down over the generations without alteration. All other chromosomes are unpredictable mixture from both parents. Only males have y chromosomes in their DNA which is passed down from father to son (exactly like the surname). In order for your family line to participate in the Reeves project, you would have to find your closest living male Reeves and have them tested. Lets assume that you grandmother was born a Reeves. The possible men that you could get to be tested (if any ever existed and are currently living) are: 1) Your grandmother's brother (your Reeves great uncle) 2) Your grandmother's bother's son (your Reeves uncle) 3) Your grandmother's brother's grandson (your male Reeves second cousin) Your next option, if none of the above exists, is to go one generation back from your grandmother. Find out if your great grandfather Reeves had any brothers, and then trace his descendents to find a living male Reeves that descends from your great great uncle Reeves. If no luck there, then keep going back on your Reeves line to trace for other branches that have produced living male Reeves. I hope this helps. If I misunderstood your question, try me again. David
