Bob, I can't help you on Milly, but I can help interpret the DNA results. I run 3 DNA projects, assist at the DNA meetings at my regional genealogy society, and speak about DNA. The "Non-Paternal Event" (NPE, as they call it in the DNA world), arises when looking for an ancestor's father (in your case a Foster man) when in reality, you probably need to find a Foster woman who gave birth to your ancestor. Look for Foster women and then look for neighbors or others nearby named Watts. I bet the out of wedlock pregnancy happened a lot back in the day, but there were no reality TV shows bragging about being 17 and pregnant :) I've heard some of the young pregnant girls/women were hidden at home or sent away somewhere to have a baby. You still have Foster DNA, it's just not on your Y line. If you did the Family Finder test (if you tested with Family Tree DNA), you will start to get Foster matches there as that portion of the database builds. Hope this helps some, Cheri Mello Torrance, CA Family Tree DNA Admin (volunteer)
