Considering this name. [name_u]Love[/name_u] the meaning (hello peacemaker 
”), love that it has history (not trendy, made up name), and love the tough, yet feminine vibe. Also lots of nickname options which is fun. My husband is not sure he likes it. The [name_m]Fred[/name_m] part, you know?
It is it too vintage next to big sister’s names [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f]? Other thoughts welcome!
I love it for all the reasons you mentioned. [name_f]Winnie[/name_f] and [name_u]Freddie[/name_u] are both pretty cute [name_f]IMO[/name_f]. I think it goes with [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f] 
Oh [name_f]Winifred[/name_f] is lovely and actually quite a perfect fit for siblings [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f]. Those are names I’d consider just as vintage and spunky as [name_f]Winifred[/name_f]!
Thank you for your feedback!
Now my husband just said he likes the name [name_f]Gwendolyn[/name_f] so much better. [name_f]IMO[/name_f] the names have similar qualities which is good. And I can see why he would be more drawn to [name_f]Gwendolyn[/name_f].
I was just really trying to have the girl’s have different first initials. Is [name_f]Genevieve[/name_f] and [name_f]Gwendolyn[/name_f] too similar for siblings? What do you think?
If you shorten [name_f]Genevieve[/name_f] to [name_f]Gen[/name_f] and [name_f]Gwendolyn[/name_f] to [name_f]Gwen[/name_f] it might be too matchy, but the long forms aren’t super matchy. I still prefer [name_f]Winifred[/name_f] though

I love [name_u]Wynn[/name_u] names [name_f]Elowen[/name_f], [name_f]Bronwen[/name_f], [name_f]Gwendolyn[/name_f], [name_f]Winifred[/name_f]. But I also can never get past the [name_m]Fred[/name_m] part of [name_f]Winifred[/name_f]. I would only use it with sisters who also have feminized names like [name_f]Henriette[/name_f], [name_f]Georgina[/name_f]/[name_f]Georgiana[/name_f], [name_f]Josephine[/name_f]. Not so much with the very feminine [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f].
The “fred” always sticks out to me for this name. It reminds me of the show The Wonder Years with [name_m]Fred[/name_m] Savage’s character and his crush on [name_f]Winnie[/name_f] [name_m]Cooper[/name_m].
I do like the suggestions you were given above - [name_f]Elowen[/name_f], [name_f]Bronwen[/name_f] and [name_f]Gwendolen[/name_f] (vs the “y” version) and feel they hold up against [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f]. Other names to consider:
[name_f]Arianwen[/name_f]
[name_f]Rhonwen[/name_f]
[name_f]Anwen[/name_f]
I would have to agree on [name_f]Winifred[/name_f], it’s so pretty and has such cute nickname choices. Much too bad your husband doesn’t like it.
Could the variation [name_f]Winifreda[/name_f] be an option? Or even Winifreya?
And any opinion on [name_f]Evangeline[/name_f]? I think it keeps to the femininity of [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f] without being too close in nature, but still can be tomboyish in it’s own right with the nicknames [name_u]Van[/name_u] and [name_u]Evan[/name_u] (à la [name_u]Evan[/name_u] [name_f]Rachel[/name_f] [name_m]Wood[/name_m]).
I love the name [name_f]Winifred[/name_f]! It is my grandmother’s name and we all call her [name_f]Winnie[/name_f]! The vintage names are coming back, jimmy [name_u]Fallon[/name_u] named his daughter [name_f]Winnie[/name_f] [name_f]Rose[/name_f]!
I love [name_f]Winifred[/name_f]!!! Please ask him to reconsider!
[name_f]Winifred[/name_f] does feel stuffy to me, but [name_f]Winnie[/name_f] and [name_u]Freddie[/name_u] make it wearable. It goes great with [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f].
[name_f]Winifred[/name_f] is lovely!
Lots of nickname potential, I’m in love with [name_f]Winnie[/name_f].
Honestly, I [name_u]LOVE[/name_u] it next to [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f]. It may seem a bit older, but I think it is gorgeous and holds its own next to the other two.
I love the nickname [name_f]Winnie[/name_f], but [name_f]Winifred[/name_f] still does feel a little harsh to me. [name_f]Gwendolyn[/name_f] is pretty but close to [name_f]Genevieve[/name_f]. My middle name is [name_f]Genevieve[/name_f] and people often confuse it with [name_f]Guinevere[/name_f], and [name_f]Gwendolyn[/name_f] feels just a step away from that. Suggestions for alternatives are [name_f]Elowen[/name_f] and [name_f]Winona[/name_f].
[name_f]Winifred[/name_f] is one of my favorite names! People seem to be thrown off by ‘fred’ but it’s really pronounced win-ih-frid. Maybe he would change his mind if he saw [name_m]Tuck[/name_m] Everlasting and how cute and feminine the name is on [name_u]Alexis[/name_u] Bledel? 
I also think [name_f]Gwendolyn[/name_f] is too close to [name_f]Genevieve[/name_f], I can see the confusion that pp mentioned.
To me, [name_f]Winifred[/name_f] is too old fashioned to be paired with [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f]. [name_f]Scarlett[/name_f] seems more fresh and new, whereas [name_f]Winifred[/name_f] seems to be stuck in the past a bit.
[name_f]Gwendolyn[/name_f] is pretty, yes, but I absolutely love [name_f]Winifred[/name_f]. Like you said, all the nickname potential and the history… And I don’t think it sounds too vintage next to [name_f]Scarlett[/name_f] and [name_f]Genevieve[/name_f], it works perfectly in my opinion.
Thank you for the feedback! Very helpful!
[name_f]Do[/name_f] you have other suggestions that might pair better? The long frilly or too vintage sounding names arent my husbands cup of tea (although I’ve been able to change his mind in the past). What sounds current, isn’t over used, and still flows well with [name_f]Scarlett[/name_f] and [name_f]Eve[/name_f] in your opinion?
