what are your thoughts on which of these three names is the best:
[name]Stella[/name], [name]Estella[/name], or [name]Estelle[/name]?
I love all three of them.
Last name is [name]Hill[/name]
Middle name would most likely be [name]Mary[/name]
My favorite is [name]Estelle[/name], but with [name]Hill[/name] as a surname I would probably choose [name]Estella[/name] instead - I don’t like when both the first name and surname end with the same sound.
[name]Estella[/name] [name]Mary[/name] [name]Hill[/name] is lovely, and has that 3-2-1 syllable count that so many Berries prize. I’d go for that! 
Out of the three, my personal choice is [name]Stella[/name] and the combination [name]Stella[/name] [name]Mary[/name] has really grown on me! My second choice would generally be [name]Estelle[/name], but since [name]Estelle[/name] and [name]Hill[/name] have the same sounding ending, it just doesn’t sound so nice. I generally like [name]Estella[/name], but I feel that it does flow the best out of the three with [name]Mary[/name] [name]Hill[/name].
Good luck!
I prefer [name]Estelle[/name]. [name]Stella[/name] always makes me think of that scene from A Streetcar Named Desire… “[name]STELLA[/name]!!”", and [name]Estella[/name] makes me think of that horrible little girl from Great Expectations.
[name]Estelle[/name] is my favorite, [name]Stella[/name] is my second favorite, I don’t like [name]Estella[/name]
I agree with this!
[name]Stella[/name] [name]Mary[/name] [name]Hill[/name] for me!
[name]Estella[/name] [name]Mary[/name] [name]Hill[/name] would flow the best. The extra syllable really makes the difference. [name]Estella[/name] would also give you the option of using [name]Stella[/name] as nickname.
I like [name]Estelle[/name] best - but that’s what I’m naming my baby in [name]August[/name]. Her nickname will be [name]Elle[/name]. Seeing your last name though, I agree with the other posters about [name]Estella[/name], and calling her [name]Stella[/name] for short. [name]Estella[/name] [name]Mary[/name] [name]Hill[/name] sounds very nice.
My favorite is [name]Estella[/name]. I think [name]Estella[/name] [name]Mary[/name] [name]Hill[/name] is a perfect name.
I love them all but I think [name]Stella[/name] is my favorite. It is modern and old at the time.
I like [name]Estelle[/name] the most, but I agree that [name]Estella[/name] would sound best with [name]Hill[/name].
