What is the relationship of Duane Jr to Millicent Winship?

To determine the relationship of Duane Jr. to Millicent Winship, we need to consider family connections typically seen in familial structures. If Duane Jr. is identified as the grandson of Millicent Winship, it implies that Millicent is his grandparent, specifically his grandmother.

This relationship occurs when one of Millicent's children (likely her child) is the parent of Duane Jr. As such, Millicent would be a generation above Duane Jr. Since grandchildren derive from their grandparents, it follows that the correct answer denotes a direct line of descent in the family tree.

In contrast, other relationships suggested, such as son, nephew, or cousin, would not align with the generational hierarchy established. A son would mean Duane Jr. is Millicent's direct offspring; a nephew would indicate that Duane Jr. is the child of Millicent's sibling, and a cousin would mean that he shares a common grandparent with another family branch. These relationships would place Duane Jr. in different positions within the family structure, ultimately rendering them inconsistent with the designation of grandson. Thus, the conclusion reached here is that Duane Jr. is indeed the grandson of Millicent Winship.
