Sienna or Cassie

I prefer Cassie, but Cassie Stevens is a bit S heavy.
Sienna Stevens is gorgeous

Sienna by a mile

Cassie

Sienna by miles and miles

Sienna Stevens is cool AF!
Cassie just makes me think “gassy”

I was going to say the same as aww in that Cassie Stevens is too much with all the S’s.

I think Sienna is much nicer.

However, Cassia is really nice and would solve the S propblem!

Would you consider Cassandra? And then Cassie as a nickname. Works great with your surname.

Cassie.
But prefer the similar (to me) Carrie.

I find Sienna Stevens too SSie.

Cassandra is a great suggestion

Cassie is beautiful

Cassie

Cassie

But prefer Cassia

Cassie, because it felt like every baby girl I've known of born in the last year and a half has been named Sienna, so it's got to the point of blandness for me. Cassie is rarer, and more classic.

(If you do go for Sienna, avoid Rose as a middle name, as that's what nearly everyone chose for some reason...)

I agree they both pretty S heavy. However when I said the names in my head. Cassie Stevens seemed very forced. Whereas, Sienna Stevens just rolled off the tongue.
I think it must depend where the repetitive sounds are

Cassie, by a mile

I would have said Sienna but it seems to have become really popular out of nowhere.

Cassie is nice but I love the suggestion of Cassia.

Sienna is a bit too popular now (there are four in DD’s class). I prefer Cassie

Sorry, I dont like either.

OP said don't comment if you don't like either!
Cassandra, Cassie for short.

Sienna!

How about the more unusual Siena?

Cassie. Gorgeous!
