Concept

In a fixed-generation family puzzle, every relationship word pins a person to a generation and a gender before any seating is possible. Anchor on the definitions: a daughter-in-law marks the person above her as a parent-in-law (one generation up); “grandfather of X” fixes a two-generation gap to X; “no daughter” forces all of a person’s own children to be sons; and “no single parent” means every parent in the tree appears as a married couple. Build the three generations from these anchors, then read off the asked relation.

Application — fixing the three generations

1. G is the daughter-in-law of D, so D is a parent-in-law of G — D belongs to the topmost generation (Gen-1).

2. B is the grandfather of A, so B is also Gen-1 and A is two generations below, in Gen-3. With “no single parent,” the Gen-1 couple is B (male) and D (female).

3. Why B and D form one couple: there are exactly eight named people, and “no single parent” forces every parent to appear as a married pair. If B and D were two separate senior couples, each would also need a named spouse in the top generation — which, together with the two daughters-in-law and the grandchild, would need more than eight people. The only count that fits eight is a single senior couple, so B and D are husband and wife: B the grandfather (male) and D the grandmother (female).

4. “B has no daughter” means every child of B&D is a son, so the entire middle generation born to B&D is male.

5. G entered the family by marriage (daughter-in-law of D), so G married one of B&D’s sons — G sits in the middle generation (Gen-2) as an in-law.

6. H is the aunt of A. Since B has no daughter, A has no blood-aunt; H must be the wife of A’s father’s brother — another Gen-2 in-law.

7. Counting the eight: Gen-1 = B, D. The named sons of B&D must come from C, E and F (all Gen-2 males). G and H are the two daughters-in-law (Gen-2). A is the lone Gen-3 grandchild. That uses all eight exactly once.

8. G is the sister-in-law of C, which fits because C is a son of B&D and G married C’s brother; “C and A are of opposite gender” is consistent with C being a son (male) of B&D.

9. E is the brother of F with no child. E and F are two of the sons C, E, F — so E sits in Gen-2 as a son of B&D, not in Gen-3.

Cross-check

Test the marriages: C is married, and since G is C’s sister-in-law, G is not C’s wife. The wife pairings among the sons and the exact type of aunt H is need not be pinned down — none of them changes who sits in E’s generation. What every reading shares is that E is a son of the senior couple and is childless, with no contradiction.

Because E is a son of the senior couple, his mother is the female of that couple — and that is D. So the mother of E is D.
