How are Chavo Guerrero and Vickie Guerrero related?

Vickie is the late Eddie Guerrero's widow. Eddie had an older brother Chavo (full name Chavito), who was much older. Chavo had a son who was more around Eddie age who they called Chavito Junior or Chavo for short. Chavo Jr is actually the Chavo you know now. So Chavo Guerrero is Vickie Guerrero's nephew by marriage.
