If I had a third girl, what would you name a sister to [name]Ruby[/name] [name]June[/name] & [name]Lucy[/name] [name]Pearl[/name]? I am stuck and not loving anything.
I’d use [name]Opal[/name] as a mn!
[name]Ruby[/name] [name]June[/name], [name]Lucy[/name] [name]Pearl[/name] and:
[name]Grace[/name]
[name]Charlotte[/name] nn [name]Charlie[/name]
[name]Amelia[/name] nn [name]Millie[/name]
[name]Matilda[/name] nn [name]Tillie[/name] ( [name]Matilda[/name] [name]Opal[/name] is so sweet!)
[name]Hadley[/name] nn Haddie
I know a [name]Maggie[/name] who is just [name]Maggie[/name] and she likes it. I prefer [name]Magnolia[/name] nn [name]Maggie[/name] or [name]Noli[/name]
I feel like [name]Baby[/name] Girl No. 3 should also have a precious stone name in her name, like [name]Opal[/name] or [name]Jade[/name]. Other name suggestions are: [name]Ivy[/name], [name]Sadie[/name], [name]Poppy[/name], [name]Maggie[/name], [name]Mae[/name], [name]Violet[/name], and [name]Olive[/name].
I think [name]Ruby[/name] and [name]Lucy[/name] both have 2 syllables, the “oo” sound and ends in -y. So I think you should switch it up a little with:
[name]Matilda[/name] “[name]Tilly[/name]”
[name]Olive[/name]
[name]Penelope[/name]
[name]Harriet[/name] “[name]Hattie[/name]”
[name]May[/name]
[name]June[/name]
[name]Clementine[/name]
[name]Eva[/name]
[name]Emmeline[/name]
[name]Molly[/name] [name]Rose[/name]
[name]Sadie[/name] [name]May[/name]
[name]Lily[/name] [name]Bess[/name]
[name]Gracie[/name] [name]Anne[/name]
[name]Ivy[/name] [name]Nell[/name]
[name]Laurie[/name] [name]Fay[/name]
[name]Billie[/name] [name]Sage[/name]
[name]Nelly[/name] [name]Eve[/name]
I would use [name]Rose[/name] as a middle name.
[name]June[/name] (month): [name]Pearl[/name] ([name]June[/name]'s birthstone): [name]Rose[/name] ([name]June[/name]'s birthflower)
[name]Ruby[/name], [name]Lucy[/name], & [name]Addy[/name] (the ending is alphabetical: by,cy,dy)
[name]Ruby[/name], [name]Lucy[/name], & [name]Cassidy[/name] (dy ending)
[name]Ruby[/name], [name]Lucy[/name], & [name]Cody[/name] (dy ending)
[name]Ruby[/name], [name]Lucy[/name], & [name]Daisy[/name]
[name]Ruby[/name], [name]Lucy[/name], & [name]Maisy[/name]
[name]Ruby[/name], [name]Lucy[/name], & [name]Melody[/name] (dy ending)
[name]Ruby[/name], [name]Lucy[/name], & [name]Moira[/name]
[name]Ruby[/name], [name]Lucy[/name], & [name]Wendy[/name] (dy ending)
I like [name]Wendy[/name] [name]Rose[/name] best! It’s so sweet but still substantial.
[name]Molly[/name] [name]Rose[/name] (I like that suggestion) with your kids!!
Not that you have to stick to a formula but both your girls have two syllable first names ending in ‘y’, with single syllable noun middle names. I’d consider for first names -
[name]Lily[/name]
[name]Ivy[/name]
[name]Daisy[/name]
[name]Milly[/name] or [name]Molly[/name]
[name]Tilly[/name]
[name]Finley[/name]
[name]Sally[/name]
[name]Mary[/name]
Middles –
[name]Rose[/name]
[name]Fleur[/name]
[name]Faith[/name]
[name]Eve[/name]
[name]Grace[/name]
[name]May[/name]
Combos I like –
[name]Lily[/name] [name]Rose[/name]
[name]Ivy[/name] [name]Grace[/name]
[name]Daisy[/name] [name]May[/name]
I love the suggestion of [name]Olive[/name]! Would go perfectly with [name]Lucy[/name] and [name]Ruby[/name]. I’m thinking [name]May[/name] for a middle name. [name]Olive[/name] [name]May[/name] - love it!
I have tried to like both [name]Opal[/name] and [name]Jade[/name] for that reason, but I just don’t. But, I have [name]Sadie[/name], [name]Poppy[/name], [name]Maggie[/name], [name]Mae[/name], [name]Violet[/name] and [name]Olive[/name] on my list. 
My Aunt’s name is [name]Wendy[/name]! I’ve always loved it, but I’m not sure my husband would go for it. [name]Wendy[/name] [name]Rose[/name] is pretty.
I like [name]Olive[/name] too, but with all of the [name]Olivia[/name]'s and [name]Oliver[/name]'s, I think I’m going to steer clear.
[name]Ruby[/name] [name]June[/name], [name]Lucy[/name] [name]Pearl[/name], and…
[name]Abby[/name]
Birdy
[name]Darcy[/name]
[name]Carly[/name]
[name]Emmy[/name]
[name]Holly[/name]
[name]Ivy[/name]
[name]Lacey[/name]
[name]Poppy[/name]
[name]Sunny[/name]
I think you should keep the two-syllable -y name theme going, it’s very adorable. And [name]Mae[/name], [name]Violet[/name], and [name]Olive[/name] would all make pretty good middles names with any of these suggestions. [name]Emmy[/name] [name]Olive[/name], [name]Lacey[/name] [name]Mae[/name], [name]Darcy[/name] [name]Violet[/name], etc…
If you don’t like opal or jade, what about amber or garnet? I like the suggestion of [name]Molly[/name]… [name]Molly[/name] [name]Amber[/name] is pretty and fits so nicely with your girls!
Other suggestions:
[name]Polly[/name]
[name]Hazel[/name]
[name]Gemma[/name]
[name]Hattie[/name]
[name]Nora[/name]
I like [name]Poppy[/name].
[name]Ruby[/name] [name]June[/name], [name]Lucy[/name] [name]Pearl[/name] and …
[name]Poppy[/name] [name]May[/name]
[name]Poppy[/name] [name]Wren[/name]
[name]Poppy[/name] [name]Quinn[/name]
[name]Poppy[/name] [name]Rose[/name]
[name]Poppy[/name] [name]Hope[/name]
Could also consider [name]Polly[/name] or [name]Posey[/name]. For some reason I also think of [name]Alice[/name], [name]Stella[/name], [name]Poet[/name] and [name]Willa[/name] when I hear the names [name]Ruby[/name] and [name]Lucy[/name].
And I like [name]Wendy[/name] [name]Rose[/name], but I always like when children are named after loved ones.
[name]Ruby[/name] [name]June[/name], [name]Lucy[/name] [name]Pearl[/name] & [name]Amelia[/name] [name]Dawn[/name]

I like the suggestions of Sadie and Isla the best do far! I’m trying not to repeat, so hopefully I don’t…
Elly/Ellie/Ella
Macy
Sophie
Zoey
Addy
Lanie
Rosie
I like the suggestion of the middle name Rose–I think Elly Rose would be beautiful. Rosie Mae would be a beautiful, less common choice.
[name]Amelia[/name] [name]Grace[/name]
I have a friend named Wendy and she has always hated it as she felt it was such a childish name, however, if you chose Gwendolyn her nn could be Wendy as a child and a more grown up nn later in life like Gwen.
Here are some terrific names ending in ‘y’ that you may like
Chloe
Emily
Bonnie
Penny/Penney
Sophie
Sally
Nell nn Nellie
Molly
Daisy
Cecily (love this one)
Mary
Alexa nn Lexi
Rose/Rosie
and @dlawsonsmith had some great suggestions love Isla Wren
