I like the sound of it. I do think [name]Benedict[/name] [name]Arnold[/name] is a negative association still. But especially in the middle…and also honestly I don’t really know how informed most people are any more (sadly).
I will say that nowadays the current Pope probably comes more quickly to mind for some people than [name]Arnold[/name], which is at least a different association (whether it is positive, negative, or neutral will depend on the person). But the name now has a very “devout Catholic” feel to it that it might not have had before.
I think the “dic” part of the name might be somewhat problematic for a kid during school years.
I’d go with [name]Benedict[/name] in the middle or [name]Bennett[/name] anywhere.
I like Benedicte with a thick French accent for a girl (which I am imagining almost like [name]Ben[/name] -a - dee with a very quiet t and the end), but not with what would be the usual American prn, which would basically be [name]Benedict[/name].
