Family members for my characters?

So, I'm looking for people to play my characters' family members. I will list off my characters in need of players for their siblings. Click their name for their bio. I really suggest reading the bios because it will provide you with much more information. Also keep in mind that you must make a bio if you want to play one of my character's siblings.

TAKEN:
Wish Darkhorse - Kendall
Birch Siebold - Florence
Esra Elfinstone - Axel
**if you have forgotten what they look like (and you are one of these three people), PM me. I have the descriptions**

Liatris Siebold:
Dahlia Siebold: Dahlia is eighteen (so she doesn't live with her family anymore). She has wavy red hair, green eyes, and medium skin. She is medium height. Dahlia and her brother Birch have never gotten along very well, and she and Liatris and Snowdrop are neutral. Her personality is a blank slate.

Wisteria Oleander:
Asterales Oleander: Aster (his nickname) is fourteen years old. He has olive skin, dark hair, and dark eyes like his siblings (he is also quite a looker). He and Wist are very close, but he hates Belladonna. Aster is a complete blank slate, but don't make him a jerk. Like Wist, he hates manners and is a little bit of a wild child.
*if you would like to play any of the Oleanders, I suggest reading Wisteria's bio. It is very important.

Hazel Kasimatis
Jace Kasimatis: He can look like anything you want to and his personality is a blank slate. He is twelve years old.

Quinine Yellowbrooke
Chase Yellowbrooke: He doesn't have a set appearance or personality so it's up to you! Chase is fourteen years of age.

If you're interested, simply state your interest. This is first come, first serve.
