I think they are both very pretty names. [name]Vanessa[/name] [name]Rose[/name] is beautiful.
[name]Vanessa[/name] is one of my guilty pleasures. I find it to be a pretty name, and it compliments [name]Isabella[/name] nicely.
I love your daughter’s name! [name]Isabella[/name] [name]Jane[/name] was on my list before I fell for just [name]Isabelle[/name]. 
Sorry, yes, to me [name]Vanessa[/name] is very dated. I knew several Vanessas who were in my age group, and I don’t really know any that much younger than me. [name]Vanessa[/name] is pretty and ultra-feminine like [name]Isabella[/name], and I think they pair quite well, but yes, it is way too dated for me. If you love it, by all means, use it, there’s nothing wrong with it, and there’s nothing wrong with using a dated name (it’s a great name). I have [name]Rachel[/name] on my list and use it regardless of the fact that so many people see it as dated, and to me, [name]Vanessa[/name] is along those lines.
Good luck!
I do not really like [name]Vanessa[/name]. It fits ok with your other daughter’s name, however, I think [name]Isabella[/name] can be paired up with something else… ([name]Emma[/name], [name]Alessandra[/name], [name]Olivia[/name], [name]Sophia[/name]), but if you like it, go for it. You should select the name that YOU are happy with. On the other hand, I think the mns [name]Jane[/name] and [name]Rose[/name] are super cute and go great together for your sibset.
I think [name]Isabella[/name] and [name]Vanessa[/name] work together because they both feel very romantic.
[name]Vanessa[/name] feels mildly 1980s to me. I think it still works. There are a few names like this where we’ve observed something similar here. [name]Sabrina[/name] and [name]Miranda[/name] are two with similar feels. They had a bit of a peak in the 1980s, but because they weren’t really top names like [name]Jessica[/name] and [name]Jennifer[/name], they don’t feel as tied to the time period to some of us. But obviously this is something where people’s taste varies.
Anyway you have some good other options to consider, but I do like [name]Isabella[/name] [name]Jane[/name] and [name]Vanessa[/name] [name]Rose[/name].
I think [name]Vanessa[/name] is a great name to pair with [name]Isabella[/name] however so did [name]Stephanie[/name] Meyers. (Reneesme’s name on her passport alias was [name]Vanessa[/name] [name]Wolf[/name]. Normally this wouldn’t make me worry and I wouldn’t label it as a Twilight name however since your older daughter in [name]Isabella[/name] I thought I’d mention the [name]Bella[/name] & [name]Nessie[/name] connection.
Otherwise, I love that [name]Vanessa[/name] is the same length as [name]Isabella[/name] and [name]Jane[/name] and [name]Rose[/name] are the same length. It’s a great and subtle connection also that both first names end in e_ _a and the middle names end with e’s. It’s absolutely perfect. If the Twilight thing doesn’t bother you, think the combo is perfection.
I love [name]Isabella[/name] and [name]Vanessa[/name] together! I think something like [name]Vanessa[/name] [name]Rosette[/name] or [name]Vanessa[/name] [name]Rosalie[/name] could work too.(unless you’re honoring someone)
I like [name]Vanessa[/name] and [name]Isabella[/name]. Feminine, cute nn potential, and they seem like sisters. Great choice.
I do like [name]Vanessa[/name] [name]Rose[/name] as a sister for [name]Isabella[/name] [name]Jane[/name]. I think that [name]Victoria[/name] [name]Rose[/name] would also work if you wanted something a little more classic!
I think [name]Vanessa[/name] is beautiful and underused. While [name]Vanessa[/name] might have been at its most popular in the 80s, it’s not a generation-defining name like [name]Jessica[/name] or [name]Ashley[/name]. I do not think it sounds dated at all.
[name]Isabella[/name] [name]Jane[/name] and [name]Vanessa[/name] [name]Rose[/name] are lovely together. If you feel like [name]Vanessa[/name] is dated, you could perhaps consider [name]Odessa[/name].
I think [name]Isabella[/name] [name]Jane[/name] and [name]Vanessa[/name] [name]Rose[/name] would be great sisters. [name]Both[/name] are lovely combos!
Sounds good together
