e project is focused on tested or testable male ALLENs, these descendancy trees have been pruned not only of daughters, but
also of male lines which are known to have gone extinct or &ldquo;daughtered out&rdquo;.  However, in some instances complete reconstructed families of
the first generation or two will be included because of their broad-based genealogical interest; in such cases males known or presumed to have died
without children will be flagged &ldquo;no known issue&rdquo;, or &ldquo;(NKI)&rdquo;.</
