A DINNER PARTY KnightKnightKnight

At a dinner party, the host invites his father’s brother-in-law, his brother’s father-in-law, his father-in-law’s brother, and his brother-in-law’s father. What’s the smallest number of guests there could be?

A dinner party solution

Males are denoted by upper case and females are denoted by lower case letters. The host is C and his guest is E. His father's brother-in-law is B or C. His brother's father-in-law is C. His father-in-law's brother is C. His brother-in-law's father is C. Therefore the smallest number of guests is 1, C.
