[name]Hi[/name]! Congrats on expecting! Some thoughts follow - hope they help!
[name]Elliot[/name] - a great name that is decidedly masculine in feel - I like it but recommend looking elsewhere since you otherwise seem to go more clearly uni or femme. Plus, I think it will bump up, given the popularity of anything that can give [name]Ellie[/name] as a nickname (although this will always be on the rarer side as a proper name for girls, I think).
[name]Ellis[/name] - I really like it, but do wonder if everyone will hear [name]Alice[/name]. Again, [name]Ellie[/name]…
[name]Finlay[/name] - I’d prefer spelling [name]Finley[/name], and while it feels trendier on boys, it’s still feeling like it might be a climber for girls. Also, names like [name]Kinley[/name], Tinley, [name]McKinley[/name] are all climbing for girls. Is this rhymey with your last name? Finla would be unexpected and cool!
Harpeth - this is pretty cool! I just think everyone will hear [name]Harper[/name] and it might be better as a middle? [name]Elspeth[/name] is a variant of [name]Elizabeth[/name] that merges this with some of the [name]Ell[/name] names you like, and I think will also stay on the low end of any [name]Ellie[/name] popularity - what do you think? I also think [name]Tennessee[/name] would be really cool. Would that be rhyme-y with your last name?
[name]Isla[/name] - yes, it’s going to climb a good bit. [name]Ayla[/name], [name]Viola[/name], [name]Ayelet[/name], [name]Twyla[/name], Hila, these hit some of the same notes and might not rise as high ([name]Ayelet[/name] and [name]Twyla[/name] especially).
[name]Sailor[/name] - Sayla? Or too much : D? I see the nautical concern, but this is cool. [name]Sailor[/name] and [name]Piper[/name] would be a little close though, maybe? What about something more subtly nautical, like [name]Marin[/name]/[name]Maren[/name]?
[name]Evelyn[/name] - aww : D. [name]Lovely[/name] to honor the family. Check this one out on the charts too, though, if you’re worried about popularity. Could [name]MIL[/name]'s name be the middle? My verdict on using a living family member’s name: totally depends on the family. It’d be odd in mine, but wouldn’t in others. [name]How[/name] would your mom feel? Honored or strange? I’d ask if you haven’t. [name]Aveline[/name] is rarer and quite pretty, although probably so close while being hard to spell that it’s not as great as it otherwise might be.
[name]Scarlett[/name] - [name]Lettie[/name] or [name]Ettie[/name] are pretty nickname options. I like this name and really like it with [name]Piper[/name], but it’s definitely up there with [name]Isla[/name] in terms of chart climbing / position right now, just FYI. [name]Crimson[/name] alludes to that red color, and feels a little boyish like [name]Piper[/name], nn [name]Sonny[/name]/[name]Sunny[/name]?
[name]Beatrice[/name] - love! And while it will climb some, at this point it’s hard to imagine climbing that much. [name]Do[/name] you like [name]Beatrix[/name]? It seems to have some extra spunk to take it closer to piper - I also think it’s the rare of the two variants, and lets you pick either [name]Bea[/name] or [name]Trixie[/name] more easily (I mean, I think [name]Beatrice[/name] could still be a [name]Trixie[/name]).
All best!
