Here's the solution to
Worksheet 2: Family Tree — Activity 2.1, with explanations for each answer based on the family tree diagram.
---
✔ Answer Key & Explanations:
---
1. Becky is the _grandmother_ of Alice.
→ Becky is the mother of Bob, and Bob is the father of Alice. So Becky is Alice’s maternal grandmother.
---
2. Jane is the _aunt_ of Mark.
→ Jane is the sister of Bob (they share the same parents: Becky and Philip). Since Bob is Mark’s father, Jane is Mark’s paternal aunt.
---
3. Laura is the _cousin_ of Rose.
→ Laura is the daughter of John, who is Jane’s husband. Jane is Bob’s sister, so John is Bob’s brother-in-law. Rose is Bob’s wife → so Laura is the child of Bob’s brother-in-law → making Laura Rose’s niece? Wait — let’s recheck.
Actually,
Rose is married to Bob.
Laura is the daughter of John and Jane. Jane is Bob’s sister → so John is Bob’s brother-in-law → Laura is Bob’s niece → which makes Laura
Rose’s niece (since Rose is Bob’s wife).
But the word “niece” is in the box, and it fits better here than “cousin”.
Wait — let’s double-check:
- Rose is Bob’s wife.
- Laura is Jane and John’s daughter.
- Jane is Bob’s sister → so Laura is Bob’s niece → therefore, Laura is Rose’s
niece (because Rose is Bob’s spouse).
✔ So correct answer:
niece
*(Note: Sometimes people say “cousin” informally, but technically, Laura is Rose’s niece.)*

4. John is the _brother-in-law_ of Bob.
→ John is married to Jane, who is Bob’s sister. So John is Bob’s brother-in-law.
---
5. Julia is the _cousin_ of Mark.
→ Julia is the daughter of Jane and John. Jane is Bob’s sister → so Julia is Bob’s niece → and since Mark is Bob’s son, Julia and Mark are first cousins.
---
6. Tony is the _great-grandson_ of Philip.
→ Philip is the father of Bob. Bob is the father of Mark. Mark is the father of Tony. So Tony is Philip’s great-grandson.
---
7. Paul is the _brother_ of Julia.
→ Paul and Julia have the same parents: Jane and John → so they are siblings → Paul is Julia’s brother.
---
8. Tony is the _grandson_ of Rose.
→ Rose is the mother of Mark. Mark is the father of Tony → so Tony is Rose’s grandson.
---
9. Rose is the _sister-in-law_ of Jane.
→ Rose is married to Bob. Jane is Bob’s sister → so Rose is Jane’s sister-in-law.
---
10. Bob is the _uncle_ of Paul.
→ Bob is the brother of Jane. Jane is Paul’s mother → so Bob is Paul’s uncle.
---
