A Bigger Family Tree

Tyler was explaining to Allison that he was going to marry his cousin Keilana when they were older.  Upon hearing this statement, I jumped in on the conversation.  The rest of it went as follows:

Me:  No, you can't marry Lana, because you can't marry your cousin.
Tyler:  Why not?
Me:  Because she's part of your family, and we don't marry family members.
Tyler:  But she's Quan.
Me:  I know.  But that's still part of our family.
Tyler:  Ohhhh.  So is Grandma and Pawpaw?
Me:  Yep.
Tyler:  And Grandpa?
Me:  Yeah, and Kandee...
Tyler:  ...and the guy she lives with?  (This is another cute story for another day.) :)
**At this point Tyler goes on listing family members names, and I confirm each one.**
Tyler (in a very awe struck voice):  Wooooow!  That's like almost EVERYbody!
