I absolutely adore both [name_u]Wren[/name_u] and [name_u]Eden[/name_u] and thought there were no issues when I added them both to my short lists. They’re the type of name I like: short, sweet and to the point. But then I realised - maybe they’re too close to [name_f]Eryn[/name_f]? I think [name_u]Eden[/name_u] is safer than [name_u]Wren[/name_u], but [name_u]Wren[/name_u] is literally the last syllable of my name (eh-ren/eh-rin, my name is a variant of [name_f]Erin[/name_f]). Are they usable? Both in the FN spot, but I do like [name_u]Wren[/name_u] in the MN spot too.
I think [name_f]Eryn[/name_f] and [name_u]Wren[/name_u] would be too close, but [name_f]Eryn[/name_f] and [name_u]Eden[/name_u] would work - they don’t actually sound all that similar.
