What are your thoughts on this combination?

I love Calum, and I love the meaning! It was on my list, but I ended up going with Kaden instead. Calum is unique--you don't run into many Calums. As for Troy, I like the meaning, but I'm not too fond of the name. In the end, though, its where your heart takes you, and as long as its a name given in love, its always perfect!
