Earlier in the day, I was “Shirley (Sherlock) Holmes,”  Nancy Drew, or “Columbo.” As mentioned previously, I’ve been documenting the ancestors of my grandchildren (their “other parent” lineage). Today, I pursued the ancestry of the spouse of a first cousin. His understanding, his father was an orphan. As an “armchair researcher”  I collected (and documented) a dozen clearly accurate records. Hypothetically speaking, I have a branch of his tree. DNA tests from “hypothetical branch…” descendants and my cousins might identify the ancestor(s) of their “orphan” great-grandfather.
