I'm so confused and I think I might be my own cousin.

I've been singing that song "I'm my own grandpa" all day.  Do you remember it? Well its stuck in my head.  Why you ask?  Well, I'm doing my family tree.  My mother did some work on my grandfather and then started on her own family tree with her cousin.  I got left my grandmother's family tree.  Well as you know when you are doing detective work - and trust me this is detective work - you hit dead ends and you turn around and go another direction.

So between the three main families that I'm researching - they intermarried 8 times, that I've found so far.  I realize back in the day you didn't travel far, but I mean spread out the gene pool.  Get some new blood.  I recently found a cousin who's descended from my great-grandfather's sister.  And I found that these families intermarried even more.  Granted when you have 8 or 9 kids it's not as bad as I make it out to be, but I think the family tree is kind of loopy.  I mean how do I show that one person's brother married that person's niece and her brother married that person's sister--in-law who is at the same time the first person's sister - or something along those lines.

I'm so confused I think I'd get lost in the lines traveling from one branch to the other.  I think I need an assistant or my mommy or something.  "Calgon, take me away!"
