Really loving this name for a dd (and think it goes well with our dc Eli & Aphra )
The only thing that would put me off is it being shortened to Cassie which I would not love.
So, what do you think of Cassia, do you think it is very likely to be shortened? What vibe to you get from it (we like quirky, not common but not batshit crazy)
We would pronounce it Cass ee ah btw.
