Carys,isla or shay

These are the 3 girl names we have agreed upon.
[name]Isla[/name] carys
[name]Carys[/name] [name]Yvonne[/name]
[name]Shay[/name] carys

I know isla is getting popular,though here in the states I have never met an isla.
Which of these combos do you feel flows best.

I have an [name]Isla[/name] so I am biased. I love it even though it is a tad popular. I live in [name]Canada[/name] and have met two other [name]Isla[/name]'s. [name]One[/name] was 3, I met her in Emerg when I took my son. The other is 18 months. My daughter is almost 10 months.

None are really my style, but I’ll cast a soft vote for [name]Isla[/name] [name]Carys[/name], purely because I think it rolls off the tongue the best. [name]Carys[/name] [name]Yvonne[/name]…there is something rhythmically odd about it, though I can’t quite pinpoint it. I think [name]Shay[/name] should stay a nickname for a longer name.

[name]Cary[/name]'s [name]Yvonne[/name] is my favorite, by far. [name]Both[/name] names are ravishing and I think the meter works well, as [name]Carys[/name] is stressed on the first syllable and [name]Yvonne[/name] is stressed on the second.

I’d say [name]Isla[/name] [name]Carys[/name] gets my first vote with [name]Carys[/name] [name]Yvonne[/name] as runner up.

[name]Carys[/name] [name]Yvonne[/name], for sure! It has a great flow (by far the best out of your choices) and I think both names are underused gems. [name]Isla[/name] [name]Carys[/name] would be in distant second place for me.

I’m torn between [name]Isla[/name] [name]Carys[/name] & [name]Carys[/name] [name]Yvonne[/name].
[name]Isla[/name] is more my personal style- it feels fun and beachy. However, [name]Carys[/name] [name]Yvonne[/name] feels more elegant and mature. I think [name]Carys[/name] is more serious and will age better

I like all three names, but [name]Carys[/name] [name]Yvonne[/name] gets my vote. I think [name]Carys[/name] is lovely and you can’t go wrong with it. [name]Isla[/name] is sweet and I don’t think it is as popular as it might seem. [name]Shay[/name] is lovely to. I really like it.

I like [name]Shay[/name], but [name]Carys[/name] [name]Yvonne[/name] ges my vote.
