[name_f]Vivienne[/name_f], [name_f]Gemma[/name_f], [name_m]Alastair[/name_m], and ______
[name_f]Edith[/name_f]
[name_f]Harriet[/name_f]
[name_f]Poppy[/name_f]
[name_f]Sybil[/name_f]
Other suggestions?
[name_f]Edith[/name_f] is the one that kind of jumped out at me here, though [name_f]Harriet[/name_f] is also very nice with the other names. [name_f]Poppy[/name_f] feels like its a slightly different style, and I’m not really a fan of [name_f]Sybil[/name_f].
Thanks for responding! 
I’m not a huge fan of [name_f]Sybil[/name_f], but I think [name_f]Sylvia[/name_f] would work very well with your other classics 
[name_f]Vivienne[/name_f], [name_f]Gemma[/name_f], [name_m]Alistair[/name_m], and [name_f]Sylvia[/name_f]
Otherwise I like [name_f]Harriet[/name_f]!
[name_f]Harriet[/name_f] is perfect!
@world_wanderer, Thanks for the suggestion of [name_f]Sylvia[/name_f]! I think [name_f]Sylvie[/name_f] would make a cute nickname
@boyandgirl Thanks for the response! It seems [name_f]Harriet[/name_f] is a favorite!
