I thought that this might be a cute idea for a little ongoing series where I post fictional sibling sets (lifted from cinema, television and/or literature; some obscure and some mainstream).
So …
Siblings: Fauna, Flora, and Merryweather. Last Name: None. Fictional “Universe”: Disney’s Sleeping Beauty (1959). 
Possible sibling names/names with the same vibe?
Thoughts on the names individually and as a set?
I think they’re very cute as a set! [name_f]My[/name_f] favourite name with this set is Meadowsweet, as it ties in with the nature theme and is a compound name like Merryweather. I also like Bluejay (b), [name_f]Bluebell[/name_f] and [name_u]Snapdragon[/name_u].

[name_f]Fauna[/name_f], [name_f]Flora[/name_f] and [name_m]Meriweather[/name_m] are so cute and fresh together!
