Help, my husband and I can’t seem to think of any favourites he keeps offering the same names I rejected for the twins: [name]Stephanie[/name], [name]Jessica[/name], [name]Lachlan[/name] and [name]Jacob[/name]. My favourites are [name]Ellen[/name], [name]Sophia[/name], [name]Rosemary[/name] for girls and [name]Harry[/name], [name]Tobias[/name], [name]Joshua[/name] for boys. Any suggestions would be greatly appreciated :).
I think the spunky [name]Tobias[/name] would work well with Miette and [name]Ruby[/name] (love your daughters names!). I love [name]Rosemary[/name] but she and [name]Ruby[/name] would share an initial. Here are some suggestions.

Miette & [name]Ruby[/name] & [name]Ellen[/name]
Miette & [name]Ruby[/name] & [name]Eliza[/name]
Miette & [name]Ruby[/name] & [name]Cassia[/name]
Of your three favorites, I think [name]Ellen[/name] flows the best with Miette and [name]Ruby[/name]. [name]Sophia[/name] is becoming so trendy, and I agree with pp that [name]Rosemary[/name] sharing the same initial with [name]Ruby[/name] could leave Miette feeling like the odd one out.
As for my suggestions, I get a very vintage/granny chic vibe from your naming style, but with a spunky twist. To that end, for first names, I would suggest:
[name]Blythe[/name]
[name]Blanche[/name]
[name]Edith[/name] (nn [name]Edie[/name])
[name]Orla[/name]
[name]Clara[/name]
[name]Clytie[/name] (this is usually a nn for Clytemnestra but the whole thing seems extravagantly long for this sibset!)
[name]Elsa[/name]/[name]Elsie[/name]
[name]Florence[/name] (nn [name]Flossie[/name])
[name]Maisie[/name]
[name]Sadie[/name]
[name]Imogen[/name] (nn [name]Gennie[/name], Imma, Mogget-my fave, and others)
[name]Lorna[/name]
[name]Vera[/name]
[name]Luella[/name]
[name]Dorothy[/name] (nn [name]Dottie[/name])
[name]Thelma[/name]
[name]Dulcie[/name]/Dulcibel
[name]Gloria[/name] (nn [name]Glory[/name], Glow)
For middle names, I love your vintage floral theme. Suggestions along that line include:
[name]Hazel[/name]
[name]Daisy[/name]
[name]Violet[/name]
[name]Iris[/name]
[name]Poppy[/name]
[name]Aster[/name]
[name]Azalea[/name]
[name]Gardenia[/name]
[name]Marigold[/name]
[name]Posey[/name]
[name]Dahlia[/name]
[name]Peony[/name]
[name]Lavender[/name]
[name]Freesia[/name]
[name]Orchid[/name]
[name]Lotus[/name]
[name]Tansy[/name]
I realize that for the second middle on your daughters you used your names. But if you’d like to continue the tradition of a second middle, here are some longer, more feminissima names along the same vein as [name]Priscilla[/name] and [name]Jessica[/name]:
[name]Margaret[/name]/[name]Marguerite[/name]
[name]Josephine[/name]
[name]Frances[/name]
[name]Georgina[/name]
[name]Leticia[/name]
[name]Wilhelmina[/name]
[name]Genevieve[/name]
[name]Lavinia[/name]
[name]Jemima[/name]
[name]Millicent[/name]
[name]Evangeline[/name]
I haven’t touched on the boys names yet, but I’ll be back! 
[name]Imogen[/name] - one of the names mentioned above - may work in your pattern as a third middle name for a girl, as one of its meanings (I’m pretty sure) is “image of her mother”. Plus it’s such a pretty name!
A couple of ideas: [name]Elodie[/name] [name]Hazel[/name] [name]Imogen[/name], [name]Geneva[/name] [name]Rose[/name] [name]Imogen[/name], [name]Seraphina[/name] [name]Willow[/name] [name]Imogen[/name]
Assuming you’d want to follow the same pattern for boys, would any of these suit you? [name]George[/name] [name]Rowan[/name] (husband’s name), [name]Dylan[/name] [name]Jasper[/name] (husband’s name), [name]Thomas[/name] [name]William[/name] (after the sweet william flower) (husband’s name).
[name]Just[/name] a few ideas. [name]Hope[/name] they’re helpful!
First of all, your twin’s names are just precious! I think that [name]Rosemary[/name] is a great idea.
