They always talked about themselves at our Tupperware Parties as one big happy family, and that, in fact, is literally true.

Angela, Bertha, Carol, Doris, Emily, Frances and Gwen can all be represented on one family tree such that every female who appears on the tree is one of seven. Their jobs are, not necessarily respectively, Lawyer, Pediatrician, Executive, Psychiatrist, Interior Designer, P.T.A. Mother, and Model. Except for Carol, who remains silent, they all make remarks, which are true, as follows:

Angela:

1. My sister-in-law is the Executive.
2. My husband is also my cousin.

Bertha: 

1. My mother's sister is Gwen's brother's mother-in-law.
2. My sister is the Model

Doris:

1. My mother is the P.T.A. Mother
2. Emily's daughter is the Psychiatrist.

Emily:

1. Doris's sister is the Pediatrician.
2. My mother is the Interior Designer.

Frances:

1. My only niece is the Psychiatrist.

Gwen:

1. Bertha is the Psychiatrist's cousin.
