Default Why is the Saturn V not the Saturn II ?

Might be a simple question, but why is the Saturn V the "V" and not the "II" ?
Correct me if I'm wrong, but I do not recall any Saturn II, III, or IV rockets.
What's the deal ??

Same reason it's the Falcon 9. Number of engines.

I'm sure Luke Strawwalker will chime-in on this, but the short version is that Saturns II, III and IV were designs that didn't make the cut as the lunar mission evolved. I'm pretty sure the Saturn V was the Saturn IV with an extra engine so the "number of engines" reason is not that far off.

Spot on. The Silverstein Committee proposed eight designs for the Saturn launch vehicles (see pic below). C-1 became the Saturn 1. A refinement of the C-1 became the Saturn 1B. C-5 became the Saturn V. If C-2, C-3, and C-4 had been built they might have been the Saturn II, III, and IV.

Referencing the illustration, is that a Titan II on top of a clustered booster on the A-1?

The book "Stages to Saturn" covers this in detail...it got even a little crazier when they started pulling ideas from one "C" proposal to another...you needed a scorecard to keep up!

No matter how carefully I organize the new folders on my hard drive when I start a new project, I still end up with a quagmire of sub-folders with unsymmetrical, unintuitive names - the derivatives seem to always follow in a manner totally unanticipated when the project started.

I suspect something similar happened as the Saturn proposals evolved.
