Naming after a deceased sibling?

It is sweet but at the same time it would be nice to keep them separate. My older brother died shortly after he was born and when we were growing up we used to remember his birthday and stuff (Like my parents would buy my brothers and I something to share) and it made him special to us even though we never met him. Also the idea of being named after a deceased sibling may cause confusion for the boy especially in his younger years. I'm sorry for your loss.
