[name_f]Lydia[/name_f]
[name_f]Lucy[/name_f]
[name_f]Verity[/name_f]
[name_f]Eve[/name_f]
[name_f]Iris[/name_f]
[name_f]Phoebe[/name_f]
[name_f]Mary[/name_f]
[name_f]Fleur[/name_f]

[name_f]Leonor[/name_f] (there are a few spellings of this)
[name_f]Eloise[/name_f]
[name_f]Philippa[/name_f]
Nice if can keep all having own starting letter.
Middle: would pair with an “English classic” (Jane, [name_f]Alice[/name_f], or [name_f]Lucy[/name_f] or [name_u]Rose[/name_u] if not used as first, etc) or tailored name (Maren, [name_u]Marion[/name_u], [name_f]Helen[/name_f], [name_f]Fleur[/name_f], [name_u]Blythe[/name_u], [name_f]Eve[/name_f], [name_f]Mary[/name_f], [name_f]Daphne[/name_f] etc).
[name_f]Betsy[/name_f] [name_f]Kate[/name_f]
I love your kids’ names together. They read easy, classic yet stylish to me. I like how they all have different initials and ending sounds - so to keep that going (sorted by ending sound):
[name_u]Zoe[/name_u], [name_f]Poppy[/name_f], [name_u]Holly[/name_u], [name_f]Naomi[/name_f], [name_u]Ivy[/name_u]
[name_f]Faye[/name_f], [name_f]May[/name_f] or [name_f]Mae[/name_f]
[name_f]Irene[/name_f], [name_f]Katherine[/name_f], [name_f]Susan[/name_f], [name_f]Yvonne[/name_f]
[name_f]Olive[/name_f], [name_f]Maeve[/name_f]
[name_f]Margaret[/name_f], [name_f]Harriet[/name_f], [name_f]Odette[/name_f], [name_f]Yvette[/name_f]
[name_f]Ruth[/name_f], [name_f]Faith[/name_f]
If you don’t mind repeating a first or middle initial, I like [name_f]Amy[/name_f], [name_u]Julie[/name_u], [name_f]Judith[/name_f], [name_f]Ellen[/name_f] and [name_u]Evelyn[/name_u] for you too.
[name_f]Kathryn[/name_f]
[name_u]Marie[/name_u]
[name_u]Louise[/name_u]
[name_f]Lucy[/name_f]
[name_u]Rose[/name_u]
[name_f]Tabitha[/name_f]
[name_f]Kate[/name_f]
[name_f]Eliza[/name_f]
[name_f]Joy[/name_f]
Congrats on #4!
Assuming you prefer to stick with classic names and not repeat first name sounds…
Try:
[name_f]Georgia[/name_f] [name_f]Mae[/name_f]
[name_f]Hallie[/name_f] [name_f]Jayne[/name_f]
[name_f]Sarah[/name_f] [name_u]Louise[/name_u]
[name_f]Ellen[/name_f] [name_f]Penelope[/name_f]
[name_f]Mary[/name_f] [name_u]Joan[/name_u]
[name_f]Vera[/name_f] [name_f]Helene[/name_f]
Hopefully these help 
Congratulations! Your kids have lovely names.
[name_f]Helen[/name_f]
[name_f]Kathryn[/name_f]
[name_f]Lucy[/name_f]
[name_f]Molly[/name_f]
[name_f]Naomi[/name_f]
[name_u]Vivian[/name_u]
Warmest congratulations!
[name_f]May[/name_f] I suggest:
[name_u]George[/name_u] [name_u]Edward[/name_u]
[name_f]Anna[/name_f] [name_f]Claire[/name_f]
[name_u]Daniel[/name_u] [name_u]John[/name_u]
[name_f]Molly[/name_f] [name_f]Caroline[/name_f] or [name_f]Molly[/name_f] [name_f]Jane[/name_f]
Congratulations! 
For first names, I’d suggest [name_f]Charlotte[/name_f], [name_f]Emily[/name_f], [name_f]Emma[/name_f], [name_f]Harriet[/name_f], [name_f]Lucy[/name_f], [name_f]Lydia[/name_f], [name_f]Sarah[/name_f] or [name_f]Sophie[/name_f].
Like [name_u]George[/name_u], [name_f]Anna[/name_f] and [name_u]Daniel[/name_u], these are strong classic names!
Are the middle names honour names? If so, then it would probably make sense to have another honour middle name, but if they are just filler names then some similar filler names could be [name_f]Elizabeth[/name_f], [name_f]Kate[/name_f], [name_u]Louise[/name_u], [name_u]Marie[/name_u] or [name_f]Mary[/name_f], [name_f]May[/name_f], and [name_u]Rose[/name_u].
For combos, I like…
[name_f]Charlotte[/name_f] [name_u]Louise[/name_u]
[name_f]Emily[/name_f] [name_f]Kate[/name_f]
[name_f]Harriet[/name_f] [name_u]Rose[/name_u]
[name_f]Lucy[/name_f] [name_f]Elizabeth[/name_f]
[name_f]Lydia[/name_f] [name_u]Marie[/name_u]
[name_f]Sophie[/name_f] [name_f]May[/name_f]
[name_u]George[/name_u], [name_f]Anna[/name_f], [name_u]Daniel[/name_u] and…
[name_f]Phoebe[/name_f]
[name_f]Charlotte[/name_f]
[name_f]Clara[/name_f]
[name_f]Lucy[/name_f]
[name_f]Cora[/name_f]
[name_f]Lydia[/name_f]
[name_u]Rose[/name_u]
[name_f]Flora[/name_f]
[name_f]Beatrice[/name_f]
[name_f]Charlotte[/name_f] was the first name to come to mind, closely followed by [name_f]Ella[/name_f] or [name_f]Eleanor[/name_f]. Possible middles - [name_f]Jane[/name_f] or [name_f]Kate[/name_f].
I would use some nonsense classical names.
[name_f]Caroline[/name_f] / [name_f]Carla[/name_f]
[name_f]Lucy[/name_f] / [name_f]Lucie[/name_f]
[name_f]Mary[/name_f] / [name_u]Marie[/name_u] / [name_u]Maria[/name_u]
[name_u]Rose[/name_u] / [name_f]Rosa[/name_f]
[name_f]Hope[/name_f]
[name_f]Olivia[/name_f]
[name_f]Grace[/name_f]
[name_f]Audrey[/name_f]
[name_u]Vivien[/name_u] / [name_u]Vivian[/name_u]
[name_f]Nora[/name_f] / [name_f]Norah[/name_f]
[name_f]Adele[/name_f]
Something more spunky but still works:
[name_f]Ines[/name_f]
[name_f]Stella[/name_f]
[name_u]June[/name_u]
[name_f]Eva[/name_f] / [name_f]Ava[/name_f]
[name_f]Cora[/name_f]
[name_f]Lily[/name_f] / [name_f]Lilia[/name_f]
[name_f]Vita[/name_f]
[name_f]Ellie[/name_f]
I’m going to go against the grain here and suggest some not quite so classics. Of course I don’t know if you will be having more children, but I like a bit of a change in pattern to round off a sibset. How about [name_f]Rosie[/name_f], [name_f]Scarlett[/name_f], [name_f]Matilda[/name_f], [name_u]Esme[/name_u], [name_u]Robin[/name_u] or [name_f]Edith[/name_f]?
I think you should go into your family history and choose a name that runs in your family. My first name, Caroline, is derived from my maternal grandfather’s name, Charles, and my middle name, Edith, was the name of two of my great-great-grandmothers. Speaking of which, Caroline Edith is also a beautiful choice to go with George Edward, Anna Claire and Daniel John.
Some of my other suggestions are
Sarah Caroline (my sister’s name is Sarah)
Mary Elizabeth (both perennially popular in the English speaking world)
Julia Grace
And
Amanda Ruth (both the names of good friends of mine).
