Hello
Expecting our first child in October but can’t decide between these names. Just looking for some help. 
We have a very common second name that is also a male name. We don’t like anything too crazy.
Which do you prefer? Are there any other similar names I’ve overlooked. Do any have strange connotations?
Aaron
Daniel
Joshua
Luke (was going to be Lukas but I think the spelling would be confusing)
Wildcard choice is Dylan but I’m not sure...
Any opinions welcome!
