First name [name_f]Olivia[/name_f] with nn. [name_f]Olive[/name_f]. We’re looking for a middle name and the only one we’ve selected so far is [name_u]Reese[/name_u].
I adore [name_f]Olivia[/name_f] nn [name_f]Olive[/name_f]! It’s on my own list. 
What about:
[name_f]Olivia[/name_f] [name_f]Greer[/name_f] (love this!)
[name_f]Olivia[/name_f] [name_f]Rosalie[/name_f]
[name_f]Olivia[/name_f] [name_f]Violet[/name_f]
[name_f]Olivia[/name_f] [name_f]Josephine[/name_f]
[name_f]Olivia[/name_f] [name_u]Wren[/name_u]
[name_f]Olivia[/name_f] [name_f]Penelope[/name_f]
[name_f]Olivia[/name_f] [name_f]Clarisse[/name_f] (or [name_f]Olivia[/name_f] [name_f]Claire[/name_f]?)
[name_f]Olivia[/name_f] [name_f]Grace[/name_f]
[name_f]Olivia[/name_f] [name_f]Joy[/name_f]
[name_f]Olivia[/name_f] [name_f]Tess[/name_f]
[name_f]Olivia[/name_f] [name_f]Poppy[/name_f]
[name_f]Olivia[/name_f] [name_f]Pearl[/name_f]
[name_f]Do[/name_f] you care about how many syllables it is? I tried to use one syllable, since [name_u]Reese[/name_u] is, and it sounded like that’s what you wanted at first, but now I’m wondering if I just read you wrong. I think [name_f]Olivia[/name_f] [name_f]Charlotte[/name_f], [name_f]Olivia[/name_f] [name_f]Camille[/name_f], and [name_f]Olivia[/name_f] [name_f]Catherine[/name_f] would be beautiful, as well!
Good luck!
[name_f]Olivia[/name_f] [name_u]Reese[/name_u] is beautiful!
