I think it’s great! Both names have a similar unique but familiar vibe, I could definitely see [name_f]Phoebe[/name_f] and [name_m]Elijah[/name_m] as siblings
I think [name_f]Phoebe[/name_f] and [name_m]Elijah[/name_m] make a nice sibling set.
I really like it - great sibset!
[name_f]Phoebe[/name_f] and [name_m]Elijah[/name_m] are both names with lots of history, and are still very stylish. The rhythm of the two names said together is quite nice and I also like how both the middle names start with G, a nice way to subtly connect two siblings.
I love it!
Sounds like an awesome sibset! The have the same vibe and complement each other.
Great together 
[name_u]Love[/name_u] it! They both have that recognizable without being trendy feel.
