It’s just occurred to me that, if I let SO have his #1 girls name, Imogen, then he might just let me indulge my not-so-inner name nerd and agree to us using something fun & adventurous in the middle spot (instead of a family name).
So berries, hit me with all your wildest, most whimsical middles for Imogen!
Blossom, Moon, Sunshine, Tigerlily, Wildflower… anything goes. 
Oooh, [name_f]Imogen[/name_f] is divine! I love her! 
Sooo sunny, sparky, and classically demure. Feels like a breath of fresh air and clean cotton. A springy name that adapts to any season of weather or mood. [name_f]Cozy[/name_f] as a well-loved book and fresh-brewed tea with bread. [name_f]Gorgeous[/name_f] name.
I also adore [name_f]Innogen[/name_f], a very similar one with the same feelings but a ton of extra wow and intrigue with some double N’s! I read that this name was what [name_m]Shakespeare[/name_m] was trying to use when he wrote is character [name_f]Imogen[/name_f], but that the N’s became written as an M in time (or, something like that). Which I love!
Here are some I’d consider with sweet [name_f]Imogen[/name_f] (some are much less GP, but I love them anyway!) …
