Are these sibling names too similar?

[Merimum]

I have a DS called Cohan (pn: Co-an) and am due another baby shortly, although don't know if it's a boy or girl. Been thinking of Cole, but worried it's too similar to Cohan when said fast. Would love some opinions.

Cohan and Jude
Cohan and Ciar
Cohan and Kian
Cohan and Cameron
Cohan and Jesse
Cohan and Cormac
Cohan and Colm
Cohan and Riley
Cohan and Ciaran

Cohan and Jonah is lovely. They sound a tiny bit clumsy together, but you're not naming a double act, and the names will only be said together while they're children.

Cohan and Cole isn't that bad either. I think it could sound like a company "Cohen & Co." But if you love it, don't be dissuaded. It's not a disaster.
