Genealogy #69: Database Research - Digging Deep

In searching Ancestry.com, I was able to find census, marriage and military records for my grandfather on my mother's side. I discovered his mother's name and then tried to search for her to see how far back I could go. I was hoping to discover ancestors in Europe. I didn't find Ancestry very helpful for this--there seemed to be very little information about her. So, I attempted a google search and viola! Someone had created a family tree and I was able to trace back several generations--not Europe, but to 1700 U.S.
