Eli and Aphra? We have other names on our shortlist. But have always loved Beatrix, Daphne and Dorothy but not sure if they "go" with my other dc?
Two things to note....
I'm not looking for opinions on the above names just whether or not you think they fit. 
I know some people don't get the concept or importance of sibling names matching, I'm not looking to get into a discussion as to whether this matters or not (it does to me)
