How is wife of F related to E?

To find how the wife of F is related to E, let's analyze the relationships step-by-step based on the clues provided in the question:

1. Identify the Generations and Couples:
- A and C are sisters: C is unmarried, which means A is the sister who is married.
- F is the brother-in-law of C: Since C is unmarried and A is her sister, F must be married to A. Thus, (F and A) form the first married couple.
- A is the paternal grandmother of D: This means D's father is the son of A (and F). Let's trace D's parents.
- D is the daughter of B: Since A is the paternal grandmother of D, B must be D's mother, and B's husband must be the son of A.

2. Determine the Son of A:
- H is the nephew of C: Since A is C's sister, C's nephew must be A's son. Therefore, H is the son of A and F.
- Since B's husband is the son of A, and H is the son of A, H must be married to B. Thus, (H and B) form the second married couple.
- B has no siblings: This is consistent with our structure, as B is married into the family and does not introduce any siblings.

3. Identify E's Position:
- E is the sister-in-law of B: Since B has no siblings, E must be the sister of B's husband, H.
- Since H is the son of A and F, and E is the sister of H, E must also be the daughter of A and F.

4. Answer the Question:
- The wife of F is A.
- Since E is the daughter of A and F, the wife of F (A) is the Mother of E.
