Some of the men tested claim or have proof of decendency from one or another of the three brothers, while others do not claim decendency from a specific brother. The ancestor name in bold indicates a documented ancestry back to the three brothers. In addition, the presence of mutations that probably are shared as opposed to separately occurring link some persons together.   
While the father of the three brothers or an even earlier ancestor might be the common link for all of those in this family group, a number of those tested have more recent common ancestors that they share with others in this group.
