We are pretty set on naming our first baby girl [name]Penelope[/name] - I’m just thinking ahead and wondering what kind of sibling names go with it. Is it silly to have such a long, girly name like [name]Penelope[/name] with something short and spunky like [name]Jack[/name]? What would good names be for a sister?
Well you can always call her [name]Nell[/name] or [name]Penny[/name].
[name]Penelope[/name] is also my first choice for a girl 
you could call her [name]Nell[/name] to fit with [name]Jack[/name] but here are some sib options from my lists :
Boys -
[name]Elliott[/name]
[name]Dominic[/name]
[name]Henry[/name]
[name]Jasper[/name]
[name]Maxwell[/name]
[name]Sebastian[/name]
[name]Theodore[/name]
[name]Everett[/name]
[name]Augustine[/name]
[name]Atticus[/name]
Girls :
[name]Beatrice[/name]
[name]Coraline[/name]
[name]Bernadette[/name]
[name]Clementine[/name]
[name]Eleanor[/name]
[name]Emmeline[/name]
[name]Fiona[/name]
[name]Genevieve[/name]
[name]Rosalie[/name]
[name]Vivienne[/name]
[name]Lorelei[/name]
[name]Anneliese[/name]
[name]Bellamy[/name]
I kind of like [name]Jack[/name] and [name]Penelope[/name] together. Personally for me, the ideal would be to have sibling names close in syllable count and similar in style. But in the end, I just think it’s best to choose names you love no matter how short or long they are. Rules are made to be broken! Here are some names for future siblings from a variety of styles (mythological/classic/traditional).

I love [name]Penelope[/name] and [name]Jack[/name] together! It is a very fresh and spunky sib set!
[name]Jack[/name] and [name]Penelope[/name] are both really nice names, but when I hear them together, I would tend to think, “Your parents must really like Lost!”
((Sorry!))
I really like the suggestions of [name]Alexander[/name], [name]Sebastian[/name], [name]Beatrice[/name], [name]Matilda[/name]
[name]Penelope[/name] and [name]Josephine[/name] ([name]Ive[/name] considered this sibset)
[name]Penelope[/name] and [name]Amelia[/name]
[name]Penelope[/name] and [name]Harvey[/name]
[name]Penelope[/name] and [name]Gilbert[/name]
To me length doesn’t really matter so much as long as the feel of the names are the same, and to me [name]Penelope[/name] and [name]Jack[/name] both have a spunky, energetic feel to them. I think they match perfectly.

No not at all! [name_m]Jack[/name_m] and [name_f]Penelope[/name_f] are nice together I hope to have a little [name_f]Penelope[/name_f] myself in the future and (if I have 5 and let’s hope I don’t) her siblings will (hopefully) be named [name_m]Theodore[/name_m], [name_f]Phoebe[/name_f], [name_u]Eloise[/name_u], & [name_m]Oliver[/name_m]. I think those sound really lovely with [name_f]Penelope[/name_f]. Sorry, I know you asked for sister names, so my favourites are [name_f]Phoebe[/name_f], [name_u]Eloise[/name_u], [name_f]Flora[/name_f], [name_f]Iris[/name_f], [name_f]Louisa[/name_f], [name_f]Amelia[/name_f], & [name_f]Genevieve[/name_f]. Congratulations!!
