Dh and I haven't really been in a hurry this time, but we figured we should get some names ready to go as we're nearing viability. DS1 is Jacob (jake) and we have identical boys on the way. We don't really want to be matchy, but we would like all of the names to kind of sound good together. Right now we're leaning towards Henry and Ian. Any thoughts? No nicknames really for either of those (I don't like hank).
Mom to Jacob, Henry and Ian

I like it.
I'm not a huge fan of the name Henry, but they all do sound good together.
Not a huge fan of Ian, but that's really just personal preference. I like names that can be easily shortened to a nickname.
As far as your MNs are concerned - I think Henry Moser and Ian Taylor sound best
