Question: Was the actor who played Cal Boreland really Richard Karn's brother in real life?
Answer: According to imdb.com: Richard has only one sister. http://uk.imdb.com/name/nm0439781/bio.

Siblings can have different last names. One might have a different father. Maybe one legally changed his name for some reason, or a man took his wife's last name (not as common, but it happens). Of course, these two actors are not actually related, but I just wanted to point this out.
