Are these names too similar?

[VBee123]

DD2 is due in a few weeks time. Our 2 year old DD is called Aurelia (pronounced Au-Ray-Lia), and OH and I both really like the name Cecilia. But are they too similar?

I also like Cecily, but OH just hears Cecil and isn't so keen.

Please be kind and don't ruin the name for us, we're about 90% sure, but I just wanted to check opinions?

Cecilia is a beautiful name, if you love it go for it.

I work with a Cecille (eel sound on the end as in cecilia without the ia) ? She has a beautiful heart and I love this name because of her. Changes it slight without the Cecil issue.

I love them. My children all have similar sounding names, think Sophie, Chloe and Hattie. Not those but similar, we didn't think about the fact that they would be known as nick names and there is the occasional 'who are you shouting' times but if any of them comes when I shout it's a bonus!
