All that redundancy makes it confusing for those trying to follow the story, and it gets to be quite a tongue-twister just saying it. So, I came up with the 'Taxonomy of Workplace Relationships' to describe who everyone is in an easy to understand manner.

Well after a couple generations even this gets cumbersome to say, so it can be worked from the other side of the 'family tree'. So, because the CEO is sooooo far back, we just call him 'Adam'. From there we go to Adam's children, grandchildren, etc. Sure this is really Christian-Judeo centric, but it's something that even my Hindu and Buhdist coworkers understand.
So, let's go back to the example story and see if it's a bit easier to understand:
