Prerequisites
How to Solve Multi-Tree Merge & Relationship Problems
Step 1: Build each family tree separately from the given statements.
Step 2: Identify the marriage that connects the two trees.
Step 3: Merge the trees by connecting the married couple.

Step 6: Answer the specific question about the relationship.
Example Problem
Example: Family 1: A and B are siblings. Family 2: X and Y are siblings. A marries X. How is B related to Y? Solution: Step 1: Family 1: A and B siblings. Step 2: Family 2: X and Y siblings. Step 3: Marriage connects A and X. Step 4: B is sibling of A, Y is sibling of X. Step 5: Through marriage, B becomes sibling-in-law of X, and thus sibling-in-law of Y. Step 6: Since B and Y are of unspecified gender, they are siblings-in-law. Answer: B is sibling-in-law of Y.
