Name-e-ology

I have amassed a (albeit small) database of people that I have met, known, or encountered,
I have noticed tendencies pertaining to groups of people with the same name, these are my findings;

{Disclaimer: Apologies to anyone who finds the following offensive, please be consoled by the fact that these are vast generalisations}

Tom:
all the Toms I have met have been desperate to have people think they are cool, and seem to change their opinions depending on who they are talking with.

Josh:
Joshs seem to be very sure of their particular views, also very focused when persuing what they need.

Sarah:
(according to haircolour) Blonde sarahs are incredibly self centred, to the point where they don't perceive anything or anyone beyond themselves as having any importance or value, they tend to take everything personally because they think that everything is about them and think they deserve to have everything.
Dark-haired sarahs are very eager to please the people around them, and tend to agree with people just to make peace.

Alex:
Alexs are elitists, they seek out very specific interests and use these as a social meter.

Elesha:
Elishas are interested in fun, they sometimes don't think very far beyond having a good time. I have only been able to get to know all the Elishas I have known, or know superficially, therefor data may be skewed.

Greg:
All the Gregs I have known have sported large sideburns and been deeply interested in music and not shaving much, they tend to say very clever and/or strange things.

Luke:
Lukes have been incredibly selfish and narrowminded.

Sean:
Seans are immature, can be incredibly nice and/or/thoughtful but have a hard time being grown-ups.

Ann:
Anns are very organised, they work hard, they also play hard.

Jenny:
Jennys tend to be vague.

Dave:
Daves are very affable and socially curious.

Elizabeth:
Elizabeths hoard things and procrastinate.

Kelly and Carly:
(Compressed due to similar findings)
Kellys and Carlys tend to be shallow and fickle, they aren't fussy about how they get what they want, as long as they get what they want.

Mel:
(mainly melanies)
All seem to hate me for no apparent reason, completely unprovoked.

Ben:
Bens are incredibly concerned with leaving an amazing impression on everyone, as a result they are usually annoying.

This is about the extent to which I know multiples of people with the same name.

Also there are probably many online resources for this sort of thing that are written by people who know what they're talking about.
