Hypothetically speaking here 
If you had two children named [name_f]Iris[/name_f] and [name_m]Leo[/name_m], what would you name their sister?
I’ve thought about it but I have this thing with sibling names looking the same length when you write them out and I can’t find anything that looks that short that I like. My top choice I think would be [name_f]Nora[/name_f]
[name_m]Just[/name_m] interested to see what you would choose?
[name_f]Nora[/name_f] would be stunning

I think [name_f]Nora[/name_f] fits very well with the other two! More ideas:

I think that while [name_f]Nora[/name_f] fits in terms of length and vintage style, it’s actually too soft. [name_m]Leo[/name_m] and [name_f]Iris[/name_f] are extremely strong names with very clear meanings. I also think that [name_f]Nora[/name_f] lessens the bold impact of [name_m]Leo[/name_m] because it repeats the “oh” sound. [name_f]Nora[/name_f], to me, is close but not the one.
