I don’t think I’d ever use [name_f]Delphia[/name_f] as a first name, but I think it would make a nice middle. It hasn’t been popular since 1914. What are your thoughts?
I prefer [name_f]Delphine[/name_f], but [name_f]Delphia[/name_f] is pretty and would definitely make a beautiful middle name.
I much prefer [name_f]Delphi[/name_f] to [name_f]Delphia[/name_f]. It’s fine as a middle name.
I prefer [name_f]Delphine[/name_f] and [name_f]Delphi[/name_f] to [name_f]Delphia[/name_f]. It’s pretty but all I think of is ‘[name_f]Phila[/name_f]-’.
I prefer [name_f]Delphina[/name_f] so [name_f]Delphia[/name_f] feels like it’s missing a letter to me. Still gives you [name_f]Delphy[/name_f] though, which is so cute 
Makes me think of [name_u]Philadelphia[/name_u], and as the daughter of a proud Pittsburgher, that means I simply cannot like it for that reason! 
[name_f]Delphine[/name_f] is gorgeous though.
I always love [name_u]Del[/name_u] names for girls. This is okay, but I prefer [name_f]Delfina[/name_f], [name_f]Delphina[/name_f] and [name_f]Delphine[/name_f]. The [name_u]Philadelphia[/name_u] thing didn’t hit me at first because I was saying it “[name_u]Del[/name_u] [name_u]FEE[/name_u] uh” instead of “[name_u]DEL[/name_u] fee uh,” so I think you can expect people to try to pronounce it a few different ways. I do agree that it would make a nice middle, though. Who really cares if they have to clarify how to spell or pronounce a middle name?
Stands out, but not too wierd.
