[name_m]Hi[/name_m] there.
[name_f]Tabitha[/name_f] [name_u]Joan[/name_u] is so cute! Here are my thoughts on your list:
Genevieve-I think that [name_f]Genevieve[/name_f] [name_f]Dolores[/name_f] looks & sounds very nice. [name_f]Genevieve[/name_f] is not my personal favorite, but I can’t pinpoint why. But it’s a perfectly nice name & it goes well w/Tabitha. It’s well known but not too common & has cute nns if you’re into those.
Verity-This is fine, but it’s not my favorite. Not sure why.
Nellie-I love love love [name_f]Nellie[/name_f]. It’s better as a nn in my opinion, but I love it enough either way. It’s good as a nn for [name_f]Eleanor[/name_f], [name_f]Eleanora[/name_f], [name_f]Ellen[/name_f], [name_f]Cornelia[/name_f] or [name_f]Penelope[/name_f].
Philippa-I like this name more in theory than actually saying it, because I never know where to put the emphasis. PHIL-ippa or Phil-LIP-uh? Either way, it’s a nice choice that goes really well w/Tabitha & [name_f]Pippa[/name_f] is adorable.
Florence-This name is a bit stuffy for my tastes, but it’s not unpleasant. I love the nn [name_f]Flora[/name_f]. [name_u]Florence[/name_u] [name_f]Dolores[/name_f] isn’t the best flow.
