关于灰姑娘 cinderella

cinder是煤渣，煤灰的意思
我想确认一下
rella是灰姑娘的名字吗？或者是ella？ 请各位帮忙

cinder毫无疑问是煤渣，煤灰
问题是Ella是其本名还只是表示女性的后缀~若是后缀含有轻蔑的意味吗？
节选原文如下：
So Ella now knew
why she'd always obeyed.

But she never stopped fighting
to have things her way.

Ella! Come practice your mandolin.

Fine, but l'll take
my own sweet time doing it.

Hurry up, now.

As she struggled
to find a way out of her gift,

she had no way of knowing
something worse was adrift.

Please get well, Mother.

Listen to me.

Only Mandy and l know about the gift.

We've never even told your father.

And you must never tell anyone else.

- l don't want anyone using it against you.
- Mother, please.

Remember, no matter
what anyone says or tells you to do,
look to yourself, Ella.

What's inside you
is stronger than any spell.

Take this, then l'll always be with you.

在文中，Ella 可理解为一种称呼或者名字
在古式英语中，Ella 表示"小淘气，美丽的女子"。
在 Cinderella 中，Ella 表示女性的后缀

怎么了？
