An Example of a Male Line Descent Tree from the MRCA in a Surname Project.
How to Diagrammatically Show Descendants' Relationships
and how to Count Unique Transmission Events(UTEs)
from the Surname Project's Most Recent Common Ancestor, the(MRCA).
This Example is from the Kerchner Surname Project.

[UTE Diagram]
UTEs from MRCA in above chart marked with a black dot. Total UTEs = 38. HN=Henry Number which shows relationships.
