I am in love with the name [name_f]Francesca[/name_f]. [name_f][/name_f] Would it be a crime if my last name is [name_m]Frantz[/name_m]? I think alliteration can work sometimes, like [name_f]Andi[/name_f] [name_m]Anderson[/name_m] from “How to Lose a [name_m]Guy[/name_m] in 10 days. [name_f][/name_f] It’s my favorite but I also like…
[name_f][/name_f][name_f]Marcella[/name_f]
[name_f][/name_f][name_f]Genevieve[/name_f]
[name_f][/name_f][name_f]Audrey[/name_f]
I don’t think it’s that bad. Yes, it’s a little sing-songy or “cartoon character-y,” but if [name_f]Francesca[/name_f] is your favorite name, I wouldn’t miss out on using it. [name_f]Francesca[/name_f] [name_m]Francisco[/name_m] would be too much in my opinion but Fr@ntz is short enough that I think it’s okay despite the similarity.
Honestly, I love it. She sounds like a children’s book character! And all the nicknames (e.g. Frankie Fr@ntz) is very cute
I personally don’t like it, not because of the alliteration, but because they’re just two forms of the same name? [name_m]Frantz[/name_m] is a form of [name_m]Franz[/name_m], the [name_m]German[/name_m] form of [name_m]Franciscus[/name_m] AKA the male [name_f]Francesca[/name_f]. So that makes it feel kind of cheesy to me? But in terms of flow and sound I think it works well.

I dont mind it. It does sound a little cartoony/character type name, but thats not really a bad thing. Especially if its the name you love.
I love [name_f]Francesca[/name_f], but I like [name_f]Genevieve[/name_f] too
[name_f][/name_f][name_f]Audrey[/name_f] is pretty, but [name_f]Marcella[/name_f] is just not one of my top go to names – maybe it’s [name_f][/name_f] that "cella " ending?
I don’t think your last name will prevent [name_f]Francesca[/name_f] from working [name_f][/name_f]- just don’t [name_f][/name_f] have her middle name start with F [name_f][/name_f]- that imo is just a bit too much alliteration
It kind of cool and catchy!
[name_f][/name_f]I do love [name_f]Francesca[/name_f] though so maybe that is helping to sway me!
I’m not usually keen on the name Francesca, but I actually quite like Francesca Frantz!
I don’t like Frankie Frantz though. It’s a bit too Marky Mark!
I like Audrey Frantz best from your names.
[name_f]Francesca[/name_f] is beautiful 
[name_m]Even[/name_m] though I can see @tallemaja[name_f][/name_f] point I actually find the name catchy and bright. Like the main protagonist of a romance novel. She’s beautiful.
[name_f]Francesca[/name_f] is a lovely name! [name_f][/name_f] It is too much for me personally, but I don’t think it is enough to keep you from using it if it is your favorite? [name_f][/name_f] I never loved [name_f]Andi[/name_f] [name_m]Anderson[/name_m] though, and am picky about how I like alliteration, but if it doesn’t bother you, I think it’s fine! [name_f][/name_f] I love [name_f]Marcella[/name_f], [name_f]Genevieve[/name_f], and [name_f]Audrey[/name_f] from the rest of your list, too, though, and think [name_f]Audrey[/name_f] [name_m]Frantz[/name_m] especially sounds lovely.
[name_f][/name_f]Good luck!
I adore the name [name_f]Francesca[/name_f]! To be honest, I think you could make it work with your last name. If you really love it, you should use it! 
I like it but I agree with PP that Frankie Frantz is a bit Marky Mark or happy pants or something a bit brand-like and cheesy. And I’m not sure Franny - my preferred nickname for Frances names - is better. I think it depends on how much of a nickname culture you have and what you think of the nicknames with Frantz. I like Marcella and Genevieve with Frantz but I don’t find Audrey an easy flow on to Frantz - I get a bit tripped by the Rs. I think Audriana or Arabella would be better. I think a four syllable name sounds especially good with your last name.
I love it [name_f][/name_f]! It can have other nicknames different from frankie because frankie frantz is a bit .. y know .. .Cessie and Cesca are cuter names anyway
