Thoughts on this sibset? (for a book)

[name_m]Hi[/name_m] Nameberries,

I was wondering if I could have your thoughts on this sibset for a book I’m currently working on.

Twins:
Girl: [name_f]Josephine[/name_f] [name_u]Allison[/name_u] S. (nn. Jo)
Boys: [name_u]Bentley[/name_u] [name_m]Ames[/name_m] S. (possible nn. Lee)

Younger sister:
[name_f]Eloise[/name_f] [name_f]Mae[/name_f] S. (possible nn. Elle)

I had a lot of trouble finding a name I liked for the twin girl. I know [name_f]Josephine[/name_f] [name_u]Allison[/name_u] is a bit of a mouthful but I’ll mostly be using [name_u]Jo[/name_u] when I write about her. I really want her middle name to be [name_u]Allison[/name_u] but I’m open to other name suggestions.

I’m not entirely sure if I’ll be using nicknames for [name_u]Bentley[/name_u] and [name_f]Eloise[/name_f], but I am pretty much set on their names.

I would love to hear any thoughts you guys might have!!
Thanks

[name_f]Matilda[/name_f] nn [name_f]Tilly[/name_f] or [name_f]Charlotte[/name_f] nn [name_f]Lotte[/name_f]?

[name_f]Josephine[/name_f] nn [name_u]Jo[/name_u]
