Male book character that is named Colin (Or something like it) that may or may not be a non-mc.

So I know this is a discussion group about books, but this isn't quite it. I recently made a list of male book characters I have come across in books, and on the list, one of the names I wrote down was "Colin"  but I have no idea what book he is from or who he is at all. If anyone here knows a Colin, please let me know. 
I wouldn't rely on this info, but I feel like he was one of those guys that wasn't the main character but still likeable??? (Even a similar name helps, maybe I wrote it wrong)
Thanks!

It would help to know what genre of books you might be reading.

Here are a couple historical romance:

Castles - main character
Romancing Mister Bridgerton - main character
A Gentle Feuding - hero's brother

Agree that it would help to know the genre!

The Secret Garden has a famous Colin.

Omg thank you all so much, I found which book he is from. Colin is the guy from Haunting Violet.
