I think of someone who seems to have everything under control, but there's a dark side to her. It's got that Peyton Place thing happening for it. Conservative and sweet and filled with terrible secrets. Nancy the dark Twinkie. I definitely think it has upper middle class energy. But... also sensible working class energy. It works perfectly for a First Lady AND a Lunch Lady. For such a simple little name Nancy has many facets!
It's a fun name, I like it.
