Nom de Plume

I've been doing research on how many authors have used
Or do use a Nom de Plume (Pen name for the American's)
Most notables are Steven King as Richard Bachman
And Nora Roberts as J.D. Robb

They already had success though. The other names for
slightly different book genres.

An obvious reason to change a name to pen name
Is that another author already has your name
John Harvey is a crime author with over 30 books, and sells in the millions
John Ross Harvey has only 5 books currently sells in the under 100s

One site I read suggested 2 syllable first name, and 1 syllable last name
kind of like Steven King and J.D. Robb, go figure.

If selling horror fiction, use a K for the last name
To be placed near King and Koontz

Romance authors should sound more female or at least
Less gender specific

Danielle Steele, theres that 2 and 1 syllable combination again

So I narrowed down some choices, from many to just two.

First is names from my jobs and residences during my lifetime
Second is a nearby town and something noone uses anymore
(Though it is a famous actor/director/writer's last name by sound
And a famous sci-fi fantasy novelist exactly)

Here they are:

1. Wentworth Vaughan
2. Markham Wells

Intelligent suggestions are welcome, idiotic ridicule by simpletons are not.

Leaning towards option 1.

This would be for further fiction efforts like crime novels, sci-fi, suspense,
Or any other genre I can write.

With luck it could get a reputable publisher to sign them.
Then it will need Twitter, facebook, email address, webpage,
And all other media visibility to help sales along.
