They all definitely work together - very timeless and classic.
Also, try:
[name]Genevieve[/name]
[name]Caroline[/name]
[name]Charlotte[/name]
Absolutely, they do! The trick with this sibling set would be to bestow each name on a daughter with the correct personality, as [name]Lillian[/name] is sweet and playful, especially with the [name]Lilly[/name]/[name]Lily[/name] nickname, [name]Beatrice[/name] is independent and no-nonsense, and [name]Cecilia[/name] is outspoken and feminine. They work beautifully together, though!
Other names you might enjoy are [name]Alice[/name], [name]Diana[/name], [name]Eleanor[/name], [name]Frances[/name], [name]Georgiana[/name], [name]Harriet[/name], [name]Irene[/name], [name]Julia[/name], [name]Katharine[/name], [name]Matilda[/name], [name]Nora[/name], [name]Opal[/name], [name]Pearl[/name], [name]Quinn[/name], [name]Rosalind[/name], [name]Stella[/name], [name]Theresa[/name], [name]Victoria[/name], and [name]Winifred[/name].
We seem to share a similar naming style, so I will share with you potential names for my future children. [name]Feel[/name] free to take apart the names and use them as you please. For girls, I like [name]Lydia[/name] [name]Caroline[/name], [name]Charlotte[/name] [name]Eliza[/name], and [name]Alice[/name] [name]Amelia[/name] (alternatively, [name]Lydia[/name] [name]Catherine[/name], [name]Caroline[/name] [name]Amelia[/name], and [name]Alice[/name] [name]Genevieve[/name]). For boys, I like [name]Nathaniel[/name] [name]James[/name] and [name]Henry[/name] [name]Oliver[/name], with potential other boys as [name]Peter[/name] [name]Benjamin[/name], [name]Thomas[/name] [name]Theodore[/name], [name]Julian[/name] [name]Patrick[/name], or [name]Peter[/name] [name]Julian[/name].
