Non-paternity events (NPEs) include any event which has caused a break in the link between an hereditary surname and the Y-chromosome resulting in a son using a different surname from that of his biological father.
NPEs are very common, maybe one in every 5 to 25 births, depending on culture. NPEs include name changes, adoptions, rape, affairs, and sperm donors.
To discover the true paternal line, a male should take a Y-DNA test at Family Tree DNA.
