 Booth is a (fictional) member of the Anglo-American Booth family, best known for producing generations of actors, as well as John Wilkes Booth, the assassin of Abraham Lincoln; because of the latter, Booth does not like to talk about the fact.For the first three seasons, details on Booth's family background were generally sketchy as he rarely mentioned his family members.He is still uncomfortable discussing his childhood and becomes especially defensive when asked about it.
