I love
Declan, like
Ezra (my nephew's name) and heartily dislike
Ephraim.
Declan Miles is nice but
Declan Thomas is gorgeous. This is a combo that I could see myself using. I like
Declan Alexander and
Declan Gabriel as well.
Ezra Jacob is nice too.
If
Jordan is important to you, it certainly works with
Ezra. It's not great with
Declan since they have similar endings, however, if you're willing to put another mn first (such as
Declan Alexander Jordan), then the flow is much better. I realize not everyone is into two mns.
Personally, I wouldn't want to be limited to a certain name or even a certain initial. In your situation, I think as your pregnancy progresses, you'll be more clear on what you want to do.
