I’m not personally a fan of the name [name]Tess[/name]; it seems TOO short and doesnt have that spunk to it imo, but it doesn’t sound bad with [name]Ruby[/name]. I’m glad [name]Ruby[/name] is growing on you! It’s a great name.
[name]Ruby[/name] & [name]Tess[/name] sound great together! I also really like [name]Lucy[/name] & [name]Tess[/name], and [name]Ruby[/name] & [name]Stella[/name] together 
I think [name]Ruby[/name] and [name]Tess[/name] are a darling sibset! Ruby and Tessa works especially well.
I personally like [name]Ruby[/name]…maybe it can grow on you too like you said. If not, here’s a few (forgive any repeats)…
[name]Mena[/name]
[name]Wren[/name]
Arden
Elle
Liv
[name]Lola[/name]
[name]Pippa[/name]
[name]Luna[/name]
[name]Aria[/name]/[name]Ari[/name]
[name]Lana[/name]
[name]Cara[/name]
[name]Quinn[/name]
[name]Hope[/name]
[name]Greta[/name]
[name]Iris[/name]
Aina
[name]Evie[/name]
So we’ve tentatively settled on [name]Ruby[/name] [name]Susanna[/name] for a first daughter, but of course I’m already scheming about daughter #2. I can’t quite get behind [name]Tess[/name], and he doesn’t like [name]Theresa[/name]/[name]Teresa[/name] or [name]Tessa[/name] as a full name. Any names you feel go particularly well with [name]Ruby[/name]?
Think any of the short ones people listed would go great. All short, spunky, and can flow with [name]Ruby[/name]!
[name]Ruby[/name] [name]Susannah[/name] is great! I agree with shutterbuglove, there are a lot of great suggestions. Good luck!
[name]Maeve[/name]
[name]Romy[/name]
[name]Freya[/name]
I love the name [name]Ruby[/name] but it’s gone from my list now it’s become so popular. I like short, spunky names too. [name]How[/name] about [name]Thea[/name], [name]Roxy[/name], [name]Edie[/name], or [name]Sylvie[/name]?
