[PER] Tracing the odd eye polygenes. A question.

 
After some time of living a happy pet life with one of my dearest friends, my brown tabby/white male Puccini has re-started breeding, and has now got three of my girls pregnant, with the first litter just born days ago. He certainly became a proven odd eye producer shortly after leaving his breeder's home, but I don't actively breed for odd eyed cats as I'm focused on chocolate/lilacs, so I didn't pay much attention to it; thinking it was a goal way too elusive to add to the equation. Improving type/quality in these rare colors is challenging enough.
Now I can't help to wonder why nobody knows for sure how the inheritance works, as it is thought to be the result of recesive polygenes. Well, I found three odd eyed cats listed in the Pandecats gallery so, without knowing exactly what I was looking for, I started with my boy's daughter, then continued with the other two. Please find all three listed below, and tracing back to  PATHFINDERS TANGLE .
 
My question is: Can any of you who have access to, or know of any odd eye / odd eyed producer cats, tell us if there is any of them, that can NOT be traced back to  PATHFINDERS TANGLE ?  Just wondering if he could be the source, or one of the sources. Even if you don't find it from the bicolor trace, bear in mind that some solid breeders also used bicolors to improve boning, expression, head structure and cobbiness.

I remember my friend Livia Buremi telling me years ago, when she was actively researching odd eye pedigrees, that she would find Softmagic Big John of Bolo behind all of them (the ones she managed to have access to). Don't know how accurate that could be, but I had a look at Big John's pedigree here http://www.easypedigreedb.com/perlore/?2;SOFTMAGIC%20BIG%20JOHN%20OF%20BOLO and, sure enough, GC IRAN FIRE FLY is in his fourth generation, hence PATHFINDERS TANGLE is in the 10th. It obviously doesn't mean that all his descendants can produce odd/blue eyes, because each generation loses 50% of each parent's genes. We can only look for the "potential/possibility of"
 
Conversely, I find interesting that while Anz Nicholas Nickleby is behind many many bicolors, his pedigree does not trace back to Pathfinders cattery (I looked back to 1962 with MISSY BOOTS P71-S68-1432-A1 CALICO APR-18-1962).
