[name_f]Do[/name_f] you think [name_f]Hattie[/name_f] and [name_f]Penelope[/name_f] would work well together as siblings? Also what are some other sibling options for [name_f]Hattie[/name_f]? So far I like:
[name_f]Hattie[/name_f] & [name_f]Violet[/name_f] ([name_f]Etta[/name_f])
[name_f]Hattie[/name_f] & [name_f]Willa[/name_f]
I like [name_f]Hattie[/name_f] and [name_f]Penelope[/name_f], and I like them together, but I feel like just [name_f]Hattie[/name_f]'s a bit nicknamey next to the formal [name_f]Penelope[/name_f]. [name_f]Hattie[/name_f] and [name_f]Violet[/name_f] is a bit better, but [name_f]Hattie[/name_f] and [name_f]Etta[/name_f] seem a bit similar together. They share a lot of the same letters. [name_f]Hattie[/name_f] and [name_f]Willa[/name_f] work well together, though, imo. I think [name_f]Harriet[/name_f] and [name_f]Penelope[/name_f] “[name_f]Hattie[/name_f] and [name_f]Poppy[/name_f]” would be lovely, or something along those lines.
[name_f]Hattie[/name_f] and [name_f]Penelope[/name_f] sound beautiful together! Especially if you nn [name_f]Penelope[/name_f] either [name_f]Ellie[/name_f] or [name_f]Nellie[/name_f] 
[name_f]Hattie[/name_f] and [name_f]Violet[/name_f] are on my list, here are a few others:
[name_f]Hattie[/name_f] & [name_f]Olive[/name_f]
[name_f]Hattie[/name_f] & [name_f]Chloe[/name_f]
[name_f]Hattie[/name_f] & [name_f]Kate[/name_f]
[name_f]Hattie[/name_f] & [name_f]Pearl[/name_f]
[name_f]Hattie[/name_f] & [name_f]Eloise[/name_f]
[name_f]Hattie[/name_f] & [name_f]Millie[/name_f]
[name_f]Hattie[/name_f] & [name_f]Lucy[/name_f]
[name_f]Hattie[/name_f] & [name_f]Phoebe[/name_f]
[name_f]Hattie[/name_f] & [name_f]Libby[/name_f]
[name_f]Hattie[/name_f] & [name_f]Clara[/name_f]
[name_f]Hattie[/name_f] & [name_f]Flora[/name_f]
[name_f]Hattie[/name_f] & [name_f]Audrey[/name_f]
[name_f]Hattie[/name_f] & [name_f]Cecily[/name_f]
[name_f]Hattie[/name_f] & [name_f]Edie[/name_f]
[name_f]Hattie[/name_f] & [name_f]Isabelle[/name_f]
[name_f]Hattie[/name_f] & [name_f]Florence[/name_f]
[name_f]Hattie[/name_f] & [name_f]Beatrice[/name_f]
[name_f]Hattie[/name_f] & [name_f]Daisy[/name_f]
I agree with @ash that [name_f]Hattie[/name_f] is nicknamey and informal next to [name_f]Penelope[/name_f]. [name_f]Hattie[/name_f] and [name_f]Nell[/name_f] are more on the same level. But I love both names, so I still think they sound cute together.
It’s been pointed out in other threads that [name_f]Hattie[/name_f] and [name_f]Etta[/name_f] are a bit odd together since they are both nicknames for [name_f]Henrietta[/name_f].
[name_f]Hattie[/name_f] and [name_f]Willa[/name_f] works the best, I think.
I personally prefer [name_f]Penelope[/name_f] and [name_f]Harriet[/name_f] nn [name_f]Hattie[/name_f]. I absolutely adore [name_f]Harriet[/name_f] and [name_f]Penelope[/name_f] both separately and together!
[name_f]My[/name_f] cousin’s name is [name_f]Harriet[/name_f] (although her nn is usually [name_u]Harri[/name_u]) and her sister is called [name_f]Eloise[/name_f]. I’ve always thought that those names are amazing together!
Ok, thank you! (:
Thank you! I love the suggestion of [name_f]Audrey[/name_f], too bad I can’t use it because it’s my cousins name ):
If I met two sisters named [name_f]Hattie[/name_f] and [name_f]Penelope[/name_f] I wouldn’t think there was anything wrong with it – actually I like both names, so I’d be pretty pleased! But I guess if you’re going for a matchy or balanced set, like others said, [name_f]Hattie[/name_f] is much more casual. [name_f]Harriet[/name_f] and [name_f]Penelope[/name_f] or [name_f]Henrietta[/name_f] and [name_f]Penelope[/name_f] feels a bit more even. Especially so if [name_f]Penelope[/name_f] gets a nickname: [name_f]Hattie[/name_f] and [name_u]Penny[/name_u], [name_f]Hattie[/name_f] and [name_f]Posy[/name_f], [name_f]Hattie[/name_f] and [name_f]Poppy[/name_f], [name_f]Hattie[/name_f] and [name_f]Nellie[/name_f] or [name_f]Hattie[/name_f] and [name_f]Nella[/name_f].
I like all of the names in your sig list, but [name_f]Willa[/name_f] is a personal favorite of mine. [name_f]Hattie[/name_f] and [name_f]Willa[/name_f] makes a great duo, too.
I like them together…but [name_f]Hattie[/name_f] seems to be a bit nicknamey next to [name_f]Penelope[/name_f]. I love [name_f]Harriette[/name_f] and [name_f]Penelope[/name_f] nn [name_f]Hattie[/name_f] and [name_f]Poppy[/name_f]…or [name_f]Henrietta[/name_f] and [name_f]Penelope[/name_f] with the same nicknames. Beautiful names! Good luck!
