I do believe the original spelling is Breckin and on another site it says the name is Irish Gaelic and means 'freckled'.
I've also seen it on a young actor Brecken Palmer
who was just in the new 'Your's, Mine and Our's' movie with his twin brother Bridger Palmer
I've seen it spelled Breckon, Brechin, and Brackin and in the surname Breckinridge. I hope this clears up some questions, it's probably spelled a bit differently in Gaelic but I'm not quite up on that particular Irish name so I'm not sure.
