Colin.
It’s spelled “Colin.” Why saddle your kid with Correction Hell?

Now that’s decided, how about Caitlyn or Caitlin?

Neither. Too trendy.
Colin. Might as well spell it correctly.

BTW, an easy way to settle your next such dispute is a quick Google search:
colin: almost 80 million hits
collin: 13 million hits
Not even close.

So, Slacker, do you think she’s likely to accept the results of the Google Fight?
This isn’t like Katherine and Catherine, where there are two common ways to spell the name. If you name your kid Collin, for the rest of his life, people are just going to assume that his parents are lousy spellers. One L, please.

Kolin.
That’ll fuck 'em.

Cathleen. That’s how that damned name is properly pronounced anyway.

Col’n.

This kind of thing happens to me all the time, which I don’t mind, because I have to (grudgingly) admit that there are two equally legitimate spellings of my name, and I know people write e-mails fast and all that. But, I draw the line at an acquaintance of mine who addressed an e-mail to me spelled the wrong way…despite the fact that it is her name also, and she spells it the same way I do!
I would spell it with one L, just to try to avoid his having to say “Colin with two L’s” for the rest of his life, the way I have to say “Sarah with an H” every single time.

Doesn’t help. “Is that Greg with one G or two?” “Two, if it only had one, would it go on the beginning or the end?”

That’s just whoosed several continents’ worth of Dopers. 
One L. Two Ls looks weird.
Concerning “Rachel,” people are always sticking that extra A in somewhere. And even then, they do it wrong!. “Rachael” is a acceptable spelling, even if it’s not the one I use. “Racheal” and “Raechel” are not.
“Rachel. With one A,” I tell people a lot of the time.
Weird. Seeing my name that many times makes it look really strange suddenly.
You think it’s weird??
And not only am I named Colin, but my cat is named Rachel. She was named by someone else and it never occurred to me that I should spell it any differently when I took her to the vet for the first time.
I am about to have a son and Colin with one L was one of my suggested names.

My wife and I are expecting a young’n soon, and we’re having trouble with the name. We’ve pretty much decided on Colin, but she think it should be Collin…

Boy or girl?

Gotta name the kid Collin. Great name, brings to mind the Collin Street Bakery, home of the “World-Famous DeLuxe Fruitcake”.
Once the kids at school find out about that, it’s lights out…

One L.
However, Hostile Dialect notwithstanding, I’m afraid you’re doomed to Correction Hell whatever you do. Calling our daughter Rachel (Google: 98 million hits) versus Rachael (14 million) hasn’t stopped the world and their spouse all wanting to sneak that extra little “a” into her name at every possible opportunity (Great-granny still hasn’t got it figured after 4 Christmases)
But at least you won’t be further contributing to the problem.

My daughter has that extra little “a” in her name and the school still spelled it wrong on her 8th grade promotion certificate. I’m afraid you can’t win, one “l” or two, you’ll be correcting people forever.
