Our surname is [name]Gray[/name]. [name]One[/name] syllable, plain.
Looking for boys names…love something that is strong, but sweet. [name]Unique[/name], but not bizarre. And timeless (will last from the cradle to old age). Examples we like so far are names such as [name]Leo[/name], [name]Xavier[/name], [name]Spencer[/name], [name]Hunter[/name]. Please let me hear your inspirations! 
Wow, I’m so jealous! [name]Gray[/name] is an amazing surname, I’d love to have it. Nothing boring about that to me. 
I really like [name]Leo[/name] [name]Gray[/name] and [name]Spencer[/name] [name]Gray[/name], [name]Hunter[/name] and [name]Xavier[/name] are a bit more on the popular side, but I still like [name]Xavier[/name] [name]Gray[/name], as well. What about:
[name]Emerson[/name] [name]Gray[/name]
[name]Ezra[/name] [name]Gray[/name]
[name]Holden[/name] [name]Gray[/name]
[name]Isaac[/name] [name]Gray[/name]
[name]Julian[/name] [name]Gray[/name]
[name]Everett[/name] [name]Gray[/name]
[name]Josiah[/name] [name]Gray[/name]
[name]Emmett[/name] [name]Gray[/name]
[name]Declan[/name] [name]Gray[/name]
[name]Sebastian[/name] [name]Gray[/name]
[name]Oliver[/name] [name]Gray[/name]
[name]Winston[/name] [name]Gray[/name]
[name]Felix[/name] [name]Gray[/name]
[name]Charles[/name] [name]Gray[/name] ([name]Charlie[/name] [name]Gray[/name] would be so cute!)
I would love to suggest [name]Zane[/name], as well, but [name]Zane[/name] [name]Gray[/name] is probably the only name I’d rule out, haha, besides names that rhyme with [name]Gray[/name] (like [name]Rene[/name]).
I think you have a lot to work with given your last name. I like [name]Leo[/name] and [name]Spencer[/name] from your list.
Could be worse. Could be [name]Smith[/name]. Or [name]Jones[/name]. What about: [name]Tobias[/name], [name]Sebastian[/name], [name]Xander[/name], [name]Zachariah[/name], [name]Jeremiah[/name], [name]Wilhelm[/name] / [name]Willem[/name], [name]Beckett[/name], [name]Samson[/name], [name]Peter[/name], [name]Quinn[/name], [name]Atticus[/name], [name]Alaric[/name], [name]Damon[/name], [name]Stefan[/name], [name]Stellan[/name], [name]Kellan[/name], [name]Erik[/name], [name]Olivier[/name], [name]Phoenix[/name], [name]Devon[/name], [name]Mikhail[/name]?
I would only avoid [name]Christian[/name] because I suppose it was used somewhere. Gorgeous surnames by the way, not plain at all.
I would use something longer for a first name, what about
[name]Bartholomew[/name] [name]Gray[/name]
[name]Samuel[/name] [name]Gray[/name]
[name]Leopold[/name] [name]Gray[/name]
[name]Heathcliff[/name] [name]Gray[/name]
[name]Nathan[/name] [name]Gray[/name]
Stellar [name]Gray[/name]
Second the suggestions of [name]Wilhelm[/name], [name]Holden[/name], [name]Declan[/name] and [name]Hudson[/name].
I love all your choices so far!
What about:
[name]Shepherd[/name]
[name]Simon[/name]
[name]Desmond[/name]
[name]Cormac[/name]
[name]Bronson[/name]
[name]Elliott[/name]
[name]Jameson[/name]
[name]Archer[/name]
I love the names [name]Xavier[/name] and [name]Leo[/name], but I think my favorite with surname is [name]Spencer[/name]. I don’t like [name]Hunter[/name] [name]Gray[/name] because it sounds like a color, like [name]Hunter[/name] [name]Green[/name]. Too wordy.
[name]Xavier[/name] [name]Grey[/name] is perfect [name]IMO[/name]
I often use [name]Grey[/name] as a middle name. My favorite was [name]William[/name] [name]Grey[/name]. So I’d say [name]Gray[/name] is an awesome last name and its not plain or boring at all.
I’d like to see [name]Theodore[/name] [name]Gray[/name]. [name]Little[/name] [name]Theo[/name] [name]Gray[/name] or [name]Teddy[/name] [name]Gray[/name] is adorable.
