[name_f]Adrienne[/name_f] [name_f]Claudette[/name_f] is my vote. I like [name_f]Adrienne[/name_f] best of your first name choices. [name_f]Rhiannon[/name_f] [name_f]Jade[/name_f] (a combo of your options would be my next favourite - with [name_f]Rhiannon[/name_f] [name_f]Nicole[/name_f] each namekind of slides into the other. [name_f]Jade[/name_f] is a nice short name to balance out [name_f]Rhiannon[/name_f])
Other possible middles:
[name_f]Harriet[/name_f] (similar to [name_f]Henrietta[/name_f], but one less syllable so might work with the longer names you’re considering as firsts)
[name_f]Nicolette[/name_f] (makes [name_f]Nicole[/name_f] feel more like your family names)
[name_f]Olivette[/name_f] (again combines [name_f]Olivia[/name_f] with the “ette” names in your family - also less common than [name_f]Olivia[/name_f])
