Hard decisions.. Good meanings.

Angie
So my little brother was taken by child services and placed with another family due to my mums domestic violence relationship and drug usage. While in care, he was mistreated, and this lead to him passing away from homicide. He was only 20 months old. 
I'm pregnant and due in February '17, but I want something from his name in my babies name whether I have a boy or girl. His name was Jamarley. (Jah-mar-lee) mum and I picked his name as I loved the name Marley. 
What would people think is a good idea? Having Marley/marleigh/marlee as a name for a boy or girl and be set with it or maybe use it as a middle name? 
Last name will be Baker. 
I always took care of my brother and he means the world to me. He would've been 3 on the 11th of July. Any suggestions would be grateful!
