Thoughts on these Cass/Cash names for boys?

General Name Discussion

I’m revising my boys list and am looking for a name that could get me a [name]Cass[/name] or [name]Cash[/name] nn. Thus far, I’m thinking of these:

[name]Cash[/name] (all by its lonesome)
[name]Cashel[/name]
[name]Caspar[/name] (too ghostly?)
[name]Caspian[/name]
[name]Cassian[/name]
[name]Castor[/name]

Which of these might be a keeper?

I like [name]Cash[/name] and [name]Cashel[/name]. They both were on my long list but husband nixed them as my dog was Kesh.

I think out of all of them [name]Cash[/name] on its own is the best. [name]Caspian[/name] isn’t terrible, reminds me of [name]Narnia[/name] if you don’t mind that reference. I think [name]Caspar[/name] is an okay name, but it still makes me think of the friendly ghost and I prefer [name]Jasper[/name] or [name]Gaspar[/name]. [name]Cashel[/name] and [name]Cassian[/name] both seem made up to me and [name]Castor[/name] reminds me of the things you put on the bottom of chairs.

[name]Caspar[/name] and [name]Caspian[/name] are my favorites of your list.

I like [name]Caspian[/name]. [name]Caspar[/name] would be my second favorite, but I like the [name]Prince[/name] [name]Caspian[/name] association over [name]Casper[/name] the Friendly Ghost…
