Each of these statements (which are true) refers to seven out of the eight living members of a family. You will find that the statement either refers to them by their personal name or through their relationship with another member. The statements are:
a) Jacob's wife's sister's husband's mother's son is Patrick's cousin's father.
b) Sia's grand-daughter's cousin's father's sister-in-law is Gerry's son-in-law's wife.
Now if Annabelle has no children, what relationship does she share with Michael?
PS: There can be two solutions to this problem.
