Picking names who belonged to people
one has known whom you think needed a good spanking.
(Emphasis mine)
As others have correctly noted, names can be used to imply a setting (example: country or era), the gender of the characters, their ethnicity, and perhaps other characteristics I haven't thought of. But beyond that, I think choice of names has little significance. Why? Because your reaction to a name has much to do with your own personal experience in life.
Suppose I use the name "Ruth" in one of my stories. Perhaps I chose that name because of a vague memory of a particularly stern teacher named "Ruth". Reader A's mother might have been named "Ruth", while reader B might have been abused as a child by a baby sitter named "Ruth", but reader C might have a despised drunken hag neighbor named "Ruth". (The possibilities are endless.)
Will all of those readers react to that name the same way?
It depends! It depends on how well the author has brought the characters to life, and I believe the choice of names has little to do with the process.
