Warner

Continuing on from my previous post, Porky Pig was created by Warner Brothers, note from the wiki page of one of the founders:

• Jack Leonard "J. L." Warner (August 2, 1892 – September 9, 1978)

Note his date of death and this excerpt from my previous post:

As you can see, Robertson died one day after his birthday... and born on Weishaar's birthday. And so we now have a "September 9(x2)" pattern-cluster. 

And so the inner twin world has provided the third September 9th!!  It's interesting to note the "Warner" surname... and his middle name Leonard-- an addition to the "Leo Theme" pattern-cluster and connecting to Megan MacGregor-- the daughter of Trish and Rob
