What do you think about [name_m]Yorick[/name_m] as a brother to [name_m]Marlon[/name_m]?
Only if you want everyone who meets him to immediately quote: “[name_m]Alas[/name_m], poor [name_m]Yorick[/name_m]! I knew him, [name_m]Horatio[/name_m].” This is one of those [name_m]Shakespeare[/name_m] lines that basically everyone knows, even if they don’t know anything about the play, or even what play it is from. [name_m]Yorick[/name_m] is just the skull in [name_m]Hamlet[/name_m], I don’t think I would ever be able to get past that, and I also think it would be annoying to have that line quoted at you your whole life.
This is one of those times where I think the Nameberry description is actually spot on.
The obvious [name_m]Shakespeare[/name_m] connotations aside (and I certainly don’t think they can be ignored in this case) I don’t think the name either looks or sounds nice. Sorry.
Now [name_m]Horatio[/name_m]…however is great! 
Sorry, but it has to be said: I have NEVER read [name_m]Hamlet[/name_m], but I know that [name_m]Yorick[/name_m] is the skull. “[name_m]Alas[/name_m], poor [name_m]Yorick[/name_m]” Again, I’m sorry.
I know a little boy called [name_m]Yorick[/name_m]. It sounded strange to me at first, but now I think it’s pretty cute.
I think with [name_m]Marlon[/name_m], [name_m]Yorick[/name_m] is rather interesting.
But yes, I think everyone will think if “[name_m]Alas[/name_m], poor [name_m]Yorick[/name_m], I know him [name_m]Horatio[/name_m]!” It’s just a thing.
Have you considered similar yet different:
[name_m]Yanick[/name_m] or [name_m]Yurick[/name_m]? Or even [name_u]Yarrow[/name_u] or [name_m]Orrin[/name_m]?
A person named [name_m]Yorick[/name_m] will hear nothing but “[name_m]Alas[/name_m], poor [name_m]Yorick[/name_m], I knew him well” for his entire life. It would be like naming your child [name_m]Inigo[/name_m] and he’d hear “You killed my father, prepare to die” for his whole life. Regardless of how great the name is, it’s too tied to a quotation that most everyone knows and will feel compelled to say to him when they meet him. I wouldn’t want to saddle a person with that for his whole life.
It’s also a vacuum cleaner brand (though spelled differently).
I actually really like it, both by itself and with [name_m]Marlon[/name_m], though I don’t know whether I’d be brave enough to use it in the first name spot. Maybe Oric, [name_m]Osric[/name_m] or [name_m]Edric[/name_m]?
I know nothing about the quote everyone is throwing out so it woudn’t bother me however. when I first looked at it, I thought it said - [name_f]Yo[/name_f] [name_m]Rick[/name_m]. So now I am thinking of some guy yelling [name_f]Yo[/name_f]! [name_m]Rick[/name_m]! Over here!! 
[name_m]Ive[/name_m] never read [name_m]Hamlet[/name_m], and i have never heard the quote everyone is speaking of. Anyway, i think [name_m]Yorick[/name_m] is kind of cool. You may also like [name_m]Ulric[/name_m] or [name_m]Yuri[/name_m].
Great name, apart from the fact it is the skull in [name_m]Hamlet[/name_m]. That ruins it for me.
The [name_m]Hamlet[/name_m] connection ruins it for me, too. [name_m]York[/name_m] is a less… jester-skull-ish.
I do know the [name_m]Hamlet[/name_m] reference, but I also think of Iorek Byrnison from His Dark Materials.
I listened to the audio books and it’s pronounced very close to [name_m]Yorick[/name_m]. Maybe that spelling would be an option to get away from the [name_m]Hamlet[/name_m] connection?
