We are due in 5 weeks, and struggling with a 2nd boy name! First son is [name]Luke[/name] [name]Benjamin[/name]. We are considering [name]Jude[/name] (but is it too similar to [name]Luke[/name]?), [name]Nathan[/name], [name]Gavin[/name] and [name]Samuel[/name]. What are your thoughts? Other ideas are also welcomed. Thanks all! 
I love [name]Jude[/name] but I do think its too close to [name]Luke[/name]. All 3 of your other choices are nice with [name]Luke[/name], I especially like [name]Samuel[/name], [name]Luke[/name] and [name]Sam[/name] would be perfect!
Other ideas:
[name]Patrick[/name]
[name]Owen[/name]
[name]Ethan[/name]
[name]Quinn[/name]
[name]Drew[/name]
[name]Zachary[/name]
[name]Jack[/name]
[name]Cole[/name]
[name]William[/name]
[name]Griffin[/name]
[name]Bryce[/name]
[name]Finn[/name]
[name]Brady[/name]
[name]Alec[/name]
[name]Charlie[/name]
I would take [name]Jude[/name] off the list. [name]Luke[/name] and [name]Jude[/name] are both one syllable names with a prominent “oo” sound. [name]Luke[/name] and [name]Judd[/name] would work though.
[name]Nathan[/name] and [name]Samuel[/name] are my favorites from your list.
[name]Nathan[/name] really jumps out at me! [name]Luke[/name] and [name]Nathan[/name] sound phenomenal together and both have a traditional feel.
