I was going through some old family photos in the attic when I stumbled upon our family tree. I studied it for a couple minutes then went back down stairs to tell my mom about the family tree. The problem is I didn't study it long enough to remember the whole thing. I only remembered a couple things about it, and recent memories. Can you help me figure out my family tree? There are two grandparents, who had two children, who both got married and had 2 more children each. Totaling 10 people in all (Alex, David, Jamie, Jessica, John, Justin, Lincoln, Martha, Mary and Tina).

1. One of Jamie's ancestors was David.

2. John's sister gave birth to Tina.

3. Mary went bowling with her nephew last Saturday.

4. Alex is cousins with one of the girls.

5. Justin married Mary.

6. Jessica is not an ancestor, nor cousin of Tina.

7. Lincoln's brother showed Justin's son his baseball cards.

Answer

Martha and David were the grandparents.

They gave birth to John and Mary.

John married Jessica, who gave birth to Lincoln and Alex.

Mary married Justin and gave birth to Tina and Jamie.

scihead Jun 17, 2005	Ok, so, I thought Jamie was a girl. Therefore, Justin could not be father to Jamie and Tina ("justin's son" clue). So, I thought that Mary bowling with her nephew was a red-herring (maybe nephew was not part of the tree?), and put Mary and Justin as Grandparents, and Martha and David as parents to Tina and Jamie. Kind of works, I think. Oh well! I thought it was fun and clever the way I answered it! :-)
Gadget Jun 18, 2005	Well Done...

scallio Sep 14, 2007	I too had a rough start because I thought Jamie was a girl but figured it out and came to the correct conclusion. Fun teaser and thankfully, much easier than your other Family Tree teaser!
