What do people think? I really like it but I am not 100% sure!
It does seem to be a popular name round here (if you were worried about that - either way). Apart from that, go with what you like!
Hate it.
Sorry, but to me it's a surname.
Why not go for plain old Harry or Henry?
My friend picked Harrison for her DS2 and I love it but she wanted to shorten it to Harry which is very popular in our area. Luckily she has since decided that it is Harrison, no shortening.
I love it and he really suits the name.
Similarily, I much prefer Jackson to Jack.
I don't see the problem with surnames as forenames! Especially for boys.
My DD has a surname for a forename and as much as I love it I often wonder what would happen if she met a man with that surname??

I quite like it, with Harry for short. Am quite shocked some people think it is 'chavvy'

I have no vested interest in the name, but it really isn't chavvy (or whateva) at all.
'Chavvy' - what, because it's originally a surname? Eh?? That just doesn't make any sense.
Also I think what qualifies a name as chavvy is the accent it's predominantly said in...think about how relatively pretty Chantelle must sound when spoken by a French person....now replace it with someone from my neck of the woods (Essex - yes, Essex - now go ahead and judge if you like) - see what I mean??
My son is called Harrison. It is my surname which will be 'lost' (in my part of our family) as my father only had one child - me - and when I finally marry dp my name will change. I thought the combination of our surnames sounded bloody good, but dp with his inverse class prejudice thought a double-barreled surname would be cloyingly middle class. Hence we compromised.
Thanks to The Mighty Boosh, all I see when I hear the name is a repulsive pink octopus/alien/thingie.
If you're not 100%, have a rethink.
We found several ancestors called Harris in our family tree, so although its a surname it was used as a first name more than a hundred years ago. Dont let its use as a surname put you off. Lots of surnames have over time flipped between first and last names anyway.
I like it

Nice name, but becoming too common for me.
Harrison Ford though - swoon
Am not keen on surnames as first names either, I'm afraid.
If you like Harry, why not name him Henry?
