I’m not a fan of [name_u]Cassidy[/name_u] for a boy.
I love [name_m]Cassiel[/name_m] But it is very close to [name_m]Castiel[/name_m] (a name that I love but the connection to Supernatural is VERY strong, tho not necessarily a bad thing)
Cassian is my 2nd choice and [name_m]Cassius[/name_m] is my 3rd I also like [name_m]Caspian[/name_m] a lot!
I’d say [name_u]Cassidy[/name_u]. I think it’s fresh for a boy and is the only one of the 4 that I think guarantees the [name_u]Cass[/name_u] pronunciation.
Cassian is my favorite boy name so obviously that one gets my vote! I also love [name_m]Cassius[/name_m] although, oddly I despite the cash pronunciation of [name_m]Cassian[/name_m] but prefer it with [name_m]Cassius[/name_m].
I did not know how much I loved [name_u]Cassidy[/name_u] on a boy until I saw this post. It really is such a good name, never been a fan of it on girls but it’s definitely a yes for me in this case.
