Opinion...

I happen to love the names Coen and Tahlan.... My husbands name is Cody... so Coen is close to his name and i kinda like that but if i do comething like Tahlan coen or coen tahlan do you think he'll be nick named TC or CT cause i dont like that at all....

Advice

I think Coen and Tahlan are very nice names, they are unique and stand out.

Koby also sounds similar to Cody if you want to consider it.

I like Koby Tatum combined.

Good Luck with finding the right name!
