It was a typical problem: descendants knew Henry wasn't the biological father of their mother, but who was? Some evidence made the search easier...oral traditions gave some clue but might be wrong. The 1920 census revealed the family structure at the time of the birth, but other facts made the task more difficult--many candidates existed.
This presentation will show how logic, analysis and correlation solved this mystery by using information obtained from those who had already tested to narrow the field of candidates. Finally, targeted testing of a finite group of candidates revealed the father. Documentary evidence completes the puzzle. The GPS and the Genetic Code of Conduct guided the work.
This example illustrates that by using simple tools you can solve those near-ancestral questions and result in a typical problem well solved.
