Questions most people don’t ask: Writers edition

Writers often awaken with questions that most people don’t ask.

At my day job, most of the people I write reports for have a last name that starts with W.  Once my mind glommed onto it, like superglue on an unlucky finger, my question for the day became:

In the USA, what is the most prevalent first letter of a last name? 

I had to phrase the question many ways, but found an answer at

https://www.answers.com/Q/What_is_the_percent_distribution_of_first_letters_in_last_names_in_the_US

 Is it the correct answer? 

I have no idea.  I’m simply assuming it’s possibly true.  

I know that old saying:

But the fact that there was any answer at all astounded me.  

I highlighted the top 2 letters.   I suppose you could say that 19.89% of the USA is full of B. S.

• A 3.75%
• B 8.96%
• C 6.38%
• D 5.65%
• E 2.03%
• F 3.63%
• G 5.34%
• H 5.59%
• I 0.76%
• J 1.36%
• K 5.70%
• L 5.24%
• M 8.28%
• N 2.13%
• O 1.63%
• P 5.27%
• Q 0.26%
• R 4.80%
• S 10.93%
• T 3.88%
• U 0.47%
• V 2.55%
• W 3.46%
• X 0.02%
• Y 0.65%
• Z 1.29%

Wonder what my next question is going to be?  The possibilities are both compelling and terrifying.
