Hey there,
Having twins, boys!
I’m lost trying to find names that are not too similar or too different.
Last name is [name]Sommer[/name],
Here are some names on our list but we are open to suggestions!
My sense is that you’re not nearly as lost as you think. I like the idea of having only one of the names end in “o”. I like all the names on your list, but would point out that both [name]Otis[/name] and [name]Lewis[/name] tend to blend right into [name]Sommer[/name], making them sound like [name]Lewis[/name] Ommer and [name]Otis[/name] Ommer, so…maybe not a name that ends in “s”.
[name]Leo[/name], [name]Carl[/name], [name]Rafe[/name], [name]Ezra[/name], [name]Arthur[/name], [name]Issac[/name], [name]Axel[/name], [name]Nash[/name], [name]Theo[/name], [name]Hugh[/name]/[name]Hugo[/name], [name]Emil[/name], [name]Viggo[/name], and Sixten strike me as being in similar categories to the names you’ve listed.
I agree-- except definitely [name]Rocco[/name]. [name]Rocco[/name] & [name]Clark[/name] share the same strong sounds and can stand up to each other well while being noticeably different.
