I love Declan. It's been a fav of mine for a long time, but it is hard to make combos for. Mine is DeclanChristopher, which is double honoring for me.I like: DeclanAvery DeclanFrancis DeclanKaiI also want to say DeclanRhys, it flows wonderfully, but I hate Rhys with a burning passion.
I do agree that DeclanRhys probably flows the best.I really like Kai, but since DH's name is Kyle, I think we'd probably go with that if we use Declan for our first son.
