"Don't you think any names carry any associations though hula? It's a bit unrealistic to think all names give exactly the same impressions."
Of course, I associate names with the people bearing the name. We all do and we therefore all have different associations, depending on who we've met with a certain name. If I meet a lovely Otis I will associate the name with this lovely person, on the other hand, if I meet an annoying Otis, I will associate it with him.
That's what names are for, for identifying people and associating their name with their person.
