Natural Middle Names That Go With Raven?

So I've always loved the name Raven and my husband and I both have natural Raven colored hair so it would be perfect for a future baby girl! (if she comes out redheaded we'll choose a different name. There is a recessive redhead gene on his side with all of his father's family having red hair) Now I'm a big hippie and want the middle name to be natural like Raven Moon Lancaster or something but idk that I like Raven Moon. Do you ladies have any suggestions? Id also like it to stick to the theme of the first name. My first born girl will be Lavender Rose Lancaster. Her theme is flowers. Raven is more nighttime themed or bird themed or magical themed. Idk. I just thought you ladies and lads may have suggestions. Thanks so much!
