So I am 8 months pregnant, I have preggo-brain COMPLETELY. We are not making any headway with the name for our third baby. I think I just need to be reminded that a first and last name can’t rhyme, because the only name I actually love is [name_f]Indigo[/name_f] and our last name is [name_u]Winslow[/name_u].
I personally don’t see anything wrong with using that name combo. They sound different enough despite ending in the same sound. And if she goes by a nn then that may help you with using it. Also, if she decides to take her spouses last name in the future then chances are it probably rhyme lol.
First of all, they don’t actually rhyme. They do both end in the long-O sound, but that’s not the same thing. Some names sound very sing-song when they end the same way, but some names sound perfectly fine. [name_f]Indigo[/name_f] [name_u]Winslow[/name_u] isn’t terrible. If that feels like the name, you should use it.
I think it’s alright, they don’t sound too rhymey to me. [name_f]Indigo[/name_f] is a lovely choice!
My younger brother is [name_m]Wyatt[/name_m] [name_m]Bryant[/name_m]–they don’t rhyme either but have similar sounds. Indingo [name_u]Winslow[/name_u] has the same ending sound, but it isn’t nearly the same thing as naming your child [name_m]David[/name_m] McDavid or something similar! I like how [name_f]Indigo[/name_f] [name_u]Winslow[/name_u] flows. And on a daily basis, how often do you actually use first and last name together?
I actually like [name_f]Indigo[/name_f] [name_u]Winslow[/name_u]!
It doesn’t exactly rhyme, just has similar sounds. I would like my name to sound like that!
My maiden name (which I have retained after my marriage) sounds as if it ends in the first 3 letters that begin my first name. I pointed this out to my mother last year and she says she never noticed or thought of it. It sounds very lovely and rhythmic, and I love it! That’s why I didn’t change my last name! 
I personally like repeating sounds in names… my son is [name_m]Travis[/name_m] [name_m]Nevin[/name_m]. Notice the repeating “[name_f]VI[/name_f]” and rhythmic similarity.
I think your daughter will love to be called [name_f]Indigo[/name_f] [name_u]Winslow[/name_u]. I think what saves the combo is that [name_f]Indigo[/name_f] is three syllables, [name_u]Winslow[/name_u] is two. Have you thought of a middle? A short, one syllable would be nice.
Some rules are made to be broken. Call her [name_f]Indigo[/name_f]!
Some short middles for you:
[name_f]Ann[/name_f]
[name_f]Belle[/name_f]
[name_u]Blair[/name_u]
[name_f]Blanche[/name_f]
[name_f]Blythe[/name_f]
[name_f]Cate[/name_f]
[name_f]Claire[/name_f]
[name_f]Cora[/name_f]
[name_f]Elle[/name_f]
[name_f]Eve[/name_f]
[name_f]Faye[/name_f]
[name_f]Greer[/name_f]
[name_f]Jane[/name_f]
[name_u]Joyce[/name_u]
[name_u]Kaye[/name_u]
[name_f]Maude[/name_f]
[name_f]Ruth[/name_f]
[name_u]Shay[/name_u]
[name_u]Tate[/name_u]
I don’t think they rhyme at all - they just end in the same sound. I think [name_f]Indigo[/name_f] is lovely and I actually like the way [name_f]Indigo[/name_f] [name_u]Winslow[/name_u] sounds.
