The audience is introduced to the Genealogical Proof Standard (GPS) and then presented with four research questions concerning a man who is currently a patriot on a closed DAR line. The closed line needs more proof before descendants may claim his service. After going through the evidence, the audience will be asked to participate in the decision on whether the conclusion has been proven for each of four research questions. The Colglazier family was said to be of Pennsylvania, but were they? Following each step of the migration backward from where they settled in Indiana to the Military District of Ohio to their origins through land, probate, military, census, and tax lists, the questions are laid out and analyzed through several analysis techniques. This lecture discusses what constitutes an exhaustive search, proof, and conflicting evidence, as well as techniques (time lines, spreadsheets, and other analysis tools) that help us see the answers in the data.
