Carpediemforlife....really like Rowan....I have a Rory and thought about Rowan or Ronan if my second was a boy (ended up being a girl - Lily)
MommyToB08 - I like Christian the best of the names you listed...I'm not a huge fan of Rodney, but some of the related names like Roderick might work for a middle name. Some of the other names that are more unusual but are related are Ryden and Royden.
Christian Ryden would be my pick.
Rodney Christian sounds good..
not a bad suggestion above.....I also like Christopher alot....my son is going to be Nicholas but I think we changed his middle name last night to Rowan. Its my grandfathers name and he has passed.
Maybe you should wait and see him and decide if he looks more like a Rodney, Christopher, or a Christian. When we had our son, we had Jaden and Ethan picked out for names and waited until we saw him to give him a name. Just an idea!
