If you for sure want a name that starts with D, I would go with [name_f]Daisy[/name_f], [name_f]Della[/name_f], or [name_f]Daphne[/name_f] as previously suggested. If you’re open to other options, I think [name_f]Violet[/name_f] would be completely perfect with sisters [name_f]Alice[/name_f], [name_f]Clara[/name_f], and [name_f]Lucy[/name_f]!
[name_f]Daphne[/name_f] was my first thought but I also love the previous suggestion(s) of [name_u]Darcy[/name_u]!
My absolute top choice for you would be Eleanor Audrey. To my ear, it just sounds like she is meant to be the sister of your girls. Other combos I like:
I would prioritize matching names in strength and spunk over letters and syllables.
I’d go with [name_f]Daisy[/name_f] [name_f]Audra[/name_f] or [name_f]Dahlia[/name_f] [name_f]Audrey[/name_f]–both are beautiful!
It would be so sweet if you kept the pattern going and used classic names with DA initials. I love the PP’s suggestion of [name_f]Daisy[/name_f] [name_f]Audra[/name_f], and was going to suggest [name_f]Diana[/name_f] [name_f]Audrey[/name_f] or [name_f]Dorothy[/name_f] [name_f]Audra[/name_f] myself and saw they’d already been mentioned!
