I really enjoyed this story. I like how she escaped and went to play football - something that would have angered her parents so much - and the fun she had there and was joined by Septimus Weasley of all people. I can see her fascination with him growing from that point and then she'd meet him again at Hogwarts.

In the sentence [was stuck longingly staring out the windows with her sisters], I think it would read more smoothly if it was 'staring longingly' instead.

Other than that, I really enjoyed this story. It didn't bother me in the least that the characters were minor ones in the books because you did enough characterisation for me to be able to see them as people rather than characters, you know what I mean?

The ending was perfect, and I enjoyed this story very very much.

Your Cedrella just longs to be free and to see the world. I like how she met Septimus as well. Septimus represents the freedom and the excitement Cedrella doesn't have in her life as a Black. Her siblings don't mind too much but Cedrella wants more out of life.
I love the last line where you tie back up to their wedding. Cedrella getting married in a garden that was not magical - perfect. She has found her freedom and her love in Septimus.
Great job with this.

I loved your characterization of Cedrella, and it's always interesting to read about less known characters like her. I could really picture the scene happening in my mind as I read it, and I like dhow you paid attentions to the little details in your story - the Muggle boys noticing that she is different, the festival...
This was really nice to read :)
Cheers ;)

I think your bio is getting a bit too long...
